1. TITLE OF THE INVENTION

FLUID MIXER TAP OR VALVE

2. FIELD AND BACKGROUND OF THE INVENTION

The present invention Fluid Mixer Tap or Valve (FMT) relates to a water/ fluid mixer tap or valve that mixes water/ fluid from two or more inlet water/ fluid supply lines and discharge mixed water/ fluid from its outlet.

Here hot and cold water/ fluids or any other two or more types of fluids from two or more inlet supply lines respectively are mixed by this Fluid Mixer Tap or Valve (FMT) before reaching the outlet, allowing in the case of hot and cold water supply lines to emerge water at any temperature between that of hot and cold water inlet supplies and in case of two or more type of inlet fluids, a mixer of fluids depending upon opening of individual handle for single handle disc cartridges or opening position of a number of tap handles in case of more number of tap handles in the present invention FMT.

In prior arts, various types of water mixer taps are available. In one type water mixer tap uses two taps one for hot water and other for cold water separately and their outlet are common from where one outlet pipe or spout is connected through which mixed water discharges. In other case two separate taps are connected separately to hot and cold water supply lines and discharging individually hot and cold water in washbasin or bath tub or in kitchen sink where mixing of water takes place. In ceramic disc cartridges water mixer taps are single handle mixer taps. They work using two ceramic disks which have holes that, when aligned, allow the water to pass. This means that disk taps only ever require a quarter turn to reach full capacity and are easily handled.

Indoor taps commonly found in bathroom or kitchen or wash area are a single-handle, double-spout tap (one spout for hot water and other for cold water) or double-handle, single-spout tap or mono block disc cartridges tap having two parallel steel armoured hose connector pipes one for cold water and other for hot water screwed in tap body.

Body of single lever tap or double-handle, single-spout tap or mono block disc cartridges tap are fitted to a washbasin or a kitchen sink or bathtubs etc. by means of horse shoes rubber washer and horse shoes metal washer with the help of bolt screwed to body of the tap. Also there are two separate water hose connector in parallel one for hot water and other for cold water screwed in the tap body at one end. Allen key spanner is required for tightening and opening of this bolt which is not a standard plumbing tools. Also both water hose connectors are having one end threaded metallic male nipple and other end threaded metallic female socket. Installation of these taps are difficult and needs additional non plumbing tool in addition to horse shoes washers and bolt. Also these hose connectors can not be used properly in non metallic taps. These mixer taps do not have interlocking mechanism between hot and cold water in which hot water will come out only when cold water valve is in open condition.

A tap, also called spigot or faucet in some regions in the world, is a valve controlling release of liquids or gas, broadly categories as 1. Water taps, 2. Beer taps, 3. Gas taps, 4. Various types of valves .

Water for baths, sinks and basins can be provided by separate hot and cold taps; this arrangement is common in older installations, particularly in public washrooms/ lavatories and utility rooms laundries. This is a costly affairs as cost of two taps may be higher and also there is a risk of scolding injuries due to hot water if water temperature is high. In kitchens and bathrooms mixer taps are commonly used in many countries. In mixer taps, hot and cold water from two valves is mixed before reaching the outlet, allowing the water to emerge at any temperature between that of the hot and cold water supplies as separately opening of two valves.

For baths and showers, mixer taps frequently incorporate some sort of pressure balancing feature so that the hot/cold mixture ratio will not be affected by transient changes in the pressure of one or the other of the supplies. Especially for baths and showers, to do this using a built-in thermostat. These are known as thermostatic mixing valves.

If separate taps are used for hot and cold water, it may not be immediately clear which tap is hot and which is cold. The hot tap generally has a red indicator while the cold tap generally has a blue or green indicator. Mixer taps may have a red-blue stripe or arrows indicating which side will give hot and which cold. Hot is on the left in many countries by default. In most countries, there is a standard arrangement of hot/cold taps. Mis-assembly of some single-valve mixer taps will exchange hot and cold even if the fixture has been plumbed correctly.

Most water, gas and fluid taps and valves have adjustable flow. Turning the knob or working the lever sets the flow rate by adjusting the size of an opening in the valve assembly, giving rise to choked flow through the narrow opening in the valve.

Globe valves uses a soft rubber or neoprene washer which is screwed down onto a valve seat in order to stop the flow.

Gate valves use a metal disc the same diameter as the pipe which is screwed into place perpendicularly to the flow, cutting it off. There is no resistance to flow when the tap is fully open as it is there in globe valve, but this type of tap rarely gives a perfect seal when closed.

Cone valves or ball valves commonly used as the service shut-off valves in more- expensive water systems and usually found in gas taps.

Hands free infrared proximity sensors used in thermostatically controlled electronic dual-purpose mixing or diverting valves are used within industrial applications to automatically provide liquids as required.

Modern bathroom and kitchen taps often use ceramic or plastic surfaces sliding against other spring-loaded ceramic surfaces or plastic washers used in many countries. These tend to require far less maintenance than traditional globe valves and when maintenance is required, the entire interior of the valve is usually replaced, often as a single pre-assembled cartridge.

In many countries bibcocks to have a vacuum breaker or backflow preventer, so that water cannot return through the bibcock from the hose. This prevents contamination of the building or public water system should there be a pressure drop. Some times a double check valve often incorporated within the body of the tap itself is required to conform with water regulations.

Various types of water mixer taps and fluid mixer valves are

1. Ceramic disc cartridge taps,

2. Non rising spindle tap,

3. Rising spindle tap,

4. Single handle mixer tap,

5. Mono block mixer tap,

6. Kitchen mixer tap.

7. Shower mixer tap,

8. Thermostatic mixer tap,

9. Twin lever mixer tap,

10. Wall mounted mixer taps,

11. Lever wall mounted kitchen tap,

12. Wall mounted kitchen tap, 13. Single handle mixer valve,

14. Thermostatic Mixing valves (TMVs).

Various types of tap cartridges available are Ceramic disc cartridge, side fixing ceramic disc cartridge, two inlet ceramic disc cartridge, two inlet joystick operated ceramic disc cartridges, open outlet ceramic disc cartridge, joy stick operated ceramic cartridges, value tap cartridges, mono block ceramic mixer cartridge, sedal cartridge, rising spindle cartridge, non rising spindle cartridge etc.

Various types of mixer valves available are single handle mixer valve, thermostatic mixing valves, Freuer faucets temperature mixing valve for touchless sensor faucet polished chrome, water temperature mixing valve, Dynafluid steam and water mixing valve etc.

The existing single lever-disc cartridges mixer tap, double lever-single spout or any other similar water mixer tap available are having tap body in upper part and have no legs or tails as part of the tap body. This make them susceptible to more damage and require more maintenance. Its cumbersome and difficult arrangement for fixing them in the sink, washbasin, bathtubs etc. make it difficult to maintain in addition to high cost.

The disadvantages with exiting mixer taps are tap body has no legs or tails as its integral part, its high cost, difficult installation using two nuts and bolts, metal horseshoes, rubber horseshoes and a box spanner for tightening two nuts and bolts, steal armoured hose pipe connectors for hot and cold water pull out taps, metal female couplers in the bottom of the tap body for connecting two hose pipe connector (pull out taps), scalding leading to some time serious injuries, thermal shock, siphoning of hot water in cold water line either due to low pressure of cold water line or the cold municipality water unavailability, clean and sediment free municipality water requirement etc. The other problem is two hose pipe connectors are parallel and connected to bottom of the pull out tap allowing less water flow rate in addition to high cost. Also removing nuts for dismantling or removing the tap body for maintenance is very difficult because of handle of box spanner and location washbasin or kitchen sink etc. The box spanner and its handle are not a standard plumbing tools. Scalding and thermal shocks to kids is also a major issue related to kids. These taps have separate tap body fitted on top of kitchen sink or washbasin or bath tub using various items like nuts-bolts, horse shoes and a special box spanner for tightening the nuts-bolts. Inside the tap body cartridge is fixed and also spout is fixed outside the tap body or inbuilt spout is available in the tap body. If nuts-bolts are not tighten properly or over the period it gets loosen than the top body will get dislocated and operating it will be uncomfortable. Also there is no interlocking mechanism between cold and hot water in delivery line such that hot water will be discharged only after the cold water has been discharged or vice versa as per inlet supply line connection.

None of the above mixer taps or valves of prior arts have interlocking of hot water with respect to cold water in discharge line of a tap or valve there by protecting user from scalding injuries and thermal shocks and also non of them have concentric plurality of legs or tails or plurality of legs or tails as part of single tap body for their cost effective and ease of fittings to surface of kitchen sinks, washbasins, bathtubs etc. or their ease of connection in water lines of shower, other pipe fittings etc. and non have innovative tap fittings like Toupling C and Taptee T.

Various embodiments of the present invention Fluid Mixer Taps or Valves (FMT) are conceived and developed to use it for household as well as in industries as an efficient, reliable, robust, easy to maintain, easy to fit and dismantled and economical substitute for the existing water mixer taps with ease of use, installation and maintenance along with interlocking mechanism for hot water delivery with respect to cold water delivery described in various embodiments of the present invention. The manufacturing of this Fluid Mixer Tap or Valve (FMT) is also easy. 3. SUMMARY OF THE INVENTION

There are twelve embodiments and further embodiments disclosed in the present invention Fluid Mixer Tap or Valve (FMT) which are developed for use in baths, kitchen sinks, wash area, bath tubs, industries, hospitals etc. according to respective embodiments and attachable to them for delivery of mixed water/ fluids.

Various embodiments of the present invention Fluid Mixer Tap or Valve (FMT) are thought of and developed and described to meet the requirement of having a tap (valve) with a tap body/ bodies and a plurality of legs or tails as its/their integral parts to be used for easy fittings to support surface and easy connection to input water/ fluid supply lines, interlocking mechanism for hot and cold water supply lines in such a way that discharge of water from the tap can only happen when the cold water tap is open and water is coming out from it as described in only in third embodiment of the present invention and in some other embodiments there are additional facility like hand operated tap to be also operated along with foot/ leg operated valve after their connections. The interlocking is described in third embodiment and foot/ leg operated valve can be connected to the Fluid Mixer Taps or Valves (FMT) described in sixth and seventh embodiments of the present invention. In some embodiments the innovative Taptee T or Toupling C are used for connection of main body of the present invention FMT to input water supply lines. In some other embodiments the main body is designed and described to be directly connected to input water supply lines without the use of the Taptee T or Toupling C.

First to Eighth embodiments of the present invention Fluid Mixer Tap or Valve (FMT) as described in figure - 1 to figure - 11 respectively comprises mainly a main body connected either to a Toupling C or a Taptee T. Ninth to Twelfth embodiments of the present invention Fluid Mixer Tap or Valve (FMT) as described in figure - 12 to figure - 13 respectively comprises only one body which is thought of and developed to provide mixing facility in a single body for connection to elbows or tees or any other suitable pipe fittings for cold and hot water or/ and raw water separately in cases where there are two/ three tap bodies and two/ three input legs or tails respectively. There are plurality of legs or tails for connection to hot water supply line, cold water supply line and/ or raw water supply line. In the further embodiments lower portion of the inner leg in first to eighth embodiment can be similar to that described in this embodiment and shown in the figure -21.

The present invention, Fluid Mixer Tap or Valve (FMT), is having a plurality of hollow legs or tails connected to a tap body or tap bodies and their respective valve seats as described in various embodiments of the present invention FMT which are not there in the prior arts like single lever ceramic discs cartridge or twin lever water mixer tap etc. Also there is no facility in the prior arts for interlocking of hot and cold water lines in such a way that hot water will come out only after cold water is discharged first as described in the third embodiment of the present invention. If there is no cold water available then hot water will not come out immediately as described in the third embodiment of the present invention. In the prior arts innovative Toupling C and Taptee T are not used which are used in some embodiments of the present invention FMT. Hot and cold water supply lines, in prior art mixer taps, are connected through two female threaded sockets at bottom of the tap body using hot/ cold steel armoured water hose connectors. Since in the prior arts there are no plurality of legs or tails as integral part of the tap body/ bodies so they can not be directly connected to pipe fittings like elbow or tee joints and can not be fitted on surface of kitchen sinks, washbasins etc. using a simple back nut. In this invention in some of preferred embodiments at least one leg can be connected if desired directly to pipe fittings like elbow or tee joints which will save money by not purchasing at least one steel armoured hose connector.

Main body of various embodiments described in this present inventions Fluid Mixer Tap or Valve (FMT] mainly comprises tap body/ bodies connected to plurality of legs or tails and spout, cartridge/ cartridges housed inside the tap body/ bodies and tap handle rotatably connected to spindle of the cartridge/ cartridges.

The other advantages of present inventions FMT are ease of its installation to a washbasin or kitchen sinks or bathtubs or any other such system using a simple back nut Nl as in first, third, fourth, sixth and eleventh embodiments of the present invention, using simple hose connectors without steel armour body for hot and cold water connection innovative Toupling C or Taptee T screwed to the outer leg of the main body of first to eighth embodiments as per various drawings described in various figures and directly connected to the main body of ninth to twelfth embodiments as per drawings described in various figures, economical in cost and easy to manufacture and installed and sturdy design and can be used in sediment free water also in some embodiments and can be used for well water also in some other embodiments without much trouble.

Third embodiment can be used for preventing scalding injuries and thermal shocks by hot water. Sixth embodiment of the present invention in conjunction with connecting foot/ leg operated valve in medical services and hospitals to be operated by hand and/ or foot. This will save a lot of water in addition to improving hygiene and in turn a lot of energy. Tenth embodiment is for use where mixing hot, cold and raw water is required in a single body tap. Eleventh embodiment is for use in kitchen sinks, washbasin sinks, bath tubs etc. without using the Taptee T or the Toupling for connection to hot and cold water supply lines. Twelfth embodiment is used as a valve for mixing two types of fluids.

In first embodiment of the present invention FMT when a tap handle is turned water from two concentric legs or tails, one connected to hot water and other to cold water lines, entered in a spout, through a concentric ports in ceramic discs cartridge when their ports are aligned or opened, after mixing them in a mixing chamber. By turning the tap handle, amount of hot and cold water is adjusted there by controlling temperature of mixed discharge water. This embodiment is developed to be fitted in washbasin, kitchen sinks or bath tubs or any such base where leg or tail is to be inserted and to be fitted in the base using a back nut and a washer. The main body A is connected to the Taptee T.

The second embodiment of the present invention FMT is same · as the first embodiment with a difference in second leg. In this embodiment second leg is an integral part of the outer leg where as in the first embodiment the second leg is not an integral part of the outer leg but it is a part of the Taptee T screwed in the first leg of the outer leg. The main body B in the second embodiment is connected to the Toupling C. ,

In the third embodiment of the present invention FMT, two concentric legs or tails are extended at their top end and are connected to valve seats of respective tap bodies which are also connected to each other and their output is connected to a mixer chamber through an interlocking mechanism for hot and cold water supply. Here the cold water line tap handle (right side handle as per figure - 3) is first turned allowing water to enter in a header there by lifting up one side (right side as per figure - 3) of a disc by rotating it by its diametrically opposite protrudes axis in one side and lowering the other half portion (left side as per figure - 3) of the disc in hot water side for allowing hot water to enter in the mixer chamber when hot water tap handle is turned thereby a mixer of hot and cold water is discharged from the tap. In this embodiment if hot water tap handle is opened first then hot water will lift the half portion of the disc which touches a disc seat of a stopper in the header there by not allowing hot water to enter in the spout and hence there no discharge of hot water out of the tap immediately. This will prevent scald injuries and thermal shock due to first opening mistakenly of hot water line tap. It can be used in kitchen sinks, washbasins, bath tubs etc.

The fourth embodiment of the present invention FMT is same as the third embodiment except interlocking mechanism in the header. In this embodiment there is no interlocking mechanism. It can be used in kitchen sinks, washbasins, bath tubs etc.

The main body of the fifth embodiment of the present invention FMT is same as that of fourth embodiment except it has second leg in the outer leg in addition to the first leg and also it has spout bent differently from the fourth embodiment. This can be used in water line for shower or in place of two separate taps for hot and cold water in wash rooms or bath rooms or any other suitable required places.

In the sixth embodiment of the present invention FMT, inner leg is connected to inner valve seat and concentric outer leg is opened directly into the spout, having two chambers one for direct water entering into the spout and other through the tap cartridge. So if this embodiment is fitted in washbasin or kitchen sink etc. and its second leg or tail is connected to a foot/ leg valve through hose connector then water can be discharged through this tap either by turning the tap handle by hand or by operating the foot valve by foot. This is a great advantage over any existing foot operated tap/ valve. It will improve hygiene condition in hospital in addition to saving water and electricity. This can be used in wash basin, kitchen sinks, washrooms, hospitals, industries etc.

The seventh embodiment of the present invention FMT is same as the sixth embodiment except its outer leg has second leg in addition to the first leg and can be used for places other than directly fitting in washbasin or kitchen sinks or wash tubs.

In the eighth embodiment of the present invention FMT, two concentric legs or tails are connected to valve seats of their respective two tap bodies and their output is connected to a mixing chamber in a header. The second leg is connected to outer leg whose primary leg is screwed with the Toupling C. Here when handles of both taps are turned, mixer of hot and cold water discharged through the tap. It can be used in wash rooms, water lines of shower, industries etc.

In the ninth embodiment of the present invention FMT, two legs or tails are separately connected to valve seat of respective tap bodies and their output is connected to a mixing chamber in a header. In this embodiment both legs are not concentric but are integral part of tap main body and also there is . no need of either Toupling C or Taptee T for connection to hot and cold water supply lines. In this embodiment first and second leg can be directly connected to pipe fittings like elbow or tee or any other suitable pipe fittings. Here when handles of both taps are opened, water - from two tap bodies mixed in a mixer chamber before discharging through the tap. It can be used in wash rooms, water lines of shower, industries etc.

The tenth embodiment of the present invention is same as the ninth embodiment except it has one more tap body connected to one more leg or tail in the outer leg and header. The mixing chamber in the header is same for all these three tap bodies. Here when all three taps' handles are opened a mixed water discharges through the tap. It can be used in wash rooms, water lines of shower, industries etc.

The eleventh embodiment of the present invention is same as the main body A of the first embodiment except a .minor changes in the concentric inner and outer leg. The inner leg is bent at its bottom end and extrudes through the outer leg in radial direction. It serves as second leg. The first leg is bottom part of the outer leg. Inner leg and outer leg are supported by supporting plates in radial direction. It does not use Taptee T or the Toupling T for connection to hot and cold water supply .lines. Mixed water is discharged when the tap handle is turned. It is Fitted easily to surface of kitchen sinks, washbasins, bath tubs etc. by using simple back nut. It can be used in kitchen sinks, bath tubs, washbasin etc.

The twelfth embodiment of the present invention is same as the eleventh embodiment except a small changes in its concentric inner and outer leg and a change in the spout. The inner and outer legs are bent at its bottom end for connection to hot and cold water lines. The spout is also designed for outer connection to other system. It does not use Taptee T or the Toupling T for connection to hot and cold water supply lines. Mixed water is discharged when the tap handle is turned. It is Fitted easily to pipe line systems. It can be used in industries, shower etc.

For the two protrudes 8aa, the two stoppers Ml are used and fitted in two opposite grooves lla of the header 13a in the figure - 3.

Figure - 19(b) describes and shows a hollow disc Zl. Figure - 19(c) describes and shows a cylinder head nut N2. Figure - 19(d) describes and shows a back nut Nl.

Figure - 20(a) describes a tap cartridge or valve assembly 3. Figure - 20(a) shows a view of a tap cartridge or valve assembly 3. The tap cartridge 3 is similar to brass body mono block ceramic discs tap cartridge available in the market with only difference is in its lower (fixed) ceramic disc 2 and upper (movable) ceramic disc Kl. The lower ceramic disc 2 is having two ports / openings each in inner port 3h and outer concentric port 3g as shown in the figure - 20(b) and (c). Figure - 20(d) shows a view of the upper disc Kl which rotates when the tap handle 1 rotates. The tap cartridge or valve assembly 3 as shown in the figure - 20 substantially comprises a body 3a, an O-ring 3b, a valve retaining nut 3d, a circlip 3e, a stem or spindle 3f, the upper (moving) ceramic disc Kl, the lower (fixed) ceramic disc K2, the retaining washers or O- rings Ra and Rb. The tap cartridge 3 is same as that of any type of standard tap cartridges suitable to be fixed and used in this first and second embodiment of the present invention as shown in the figure-1 and figure-2. The cartridge 3 can be spindle- washers type also. In this type of cartridge there can be one washer covering both inner valve seat 4a and outer valve seat 4b or can have two concentric washer designed to suit the requirement in the present invention. The tap cartridge 3 is housed in the tap body 2 and the stem or spindle 3f is tightened to the tap handle 1 by a screw.

Figure - 21 discloses a lower portion of an inner leg 8z having two parts 8za and 8zb. The lower portion 8zb is having hose barb 8zf at top end, circular disc protrude 8zd near middle end and threaded end at bottom side for connection to the lock nut N2. There are various inner legs e.g. 8 in the First and Second embodiment, 15a in the Third to Fifth embodiment, 6b in the Sixth and Seventh embodiment and 13d in the Eighth embodiment of the present invention FMT. Hollow disc Zl inserted in the above said inner legs in the first to the eighth embodiments. This combination of the inner leg and the disc Zl can be replaced by the inner leg comprising of the 8za-8ze, the 8zb-8zd-8zf and a connecting pipe 8zc as shown in the figure -19. The advantage will be that the chances of breakage of the inner leg as shown in the first to eighth embodiment due to opening of the taptee T or the toupling C from the main body of embodiments shown in Figure-1 to Figure-11 without removing the lock nut N2 can be ruled out. A. FIRST EMBODIMENT

Figure - 1 describes the First Embodiment of the present invention Fluid Mixer Tap (FMT). Partly cross sectional and partly perspective view of the First Embodiment of the present invention is shown in Figure - 1.

The Fluid Mixer Tap illustrated in Figure -1 substantially comprises the main body A and the Taptee T screwed in the main body A.

The main body A substantially comprises the tap body 2, the tap handle 1, the tap cartridge 3, the outlet spout 14 and the two concentric tubular legs or tails named inner leg 8 and outer leg 7. The spout 14 and the two concentric legs 7 and

8 connected by the plates 6 are an integral part of the tap body 2 and can be moulded or casted in a single moulding die or casting die.

The inner leg 8 is a hollow tube with plain outer surface except threaded end

9 near its bottom end and top end is connected to the valve seat 4a opened in the tap body 2. Outer diameter of the plain surface is more than outer diameter of the threaded end 9 of the inner leg 8.

The outer leg 7 is a hollow tube having threaded outer surface for engaging the nut Nl for the purpose of fixing and tightening the main body A to surface of washbasin, kitchen sinks, bath tubs or any other surface by screwing in the nut Nl. Top end of the outer leg 7 is connected to bottom surface of outer coaxial holes in lower ring of the tap body 2 and opened inside the tap body 2 connecting to the outer valve seat 4b and bottom end is opened for connection to the Taptee T.

The spout 14 is a hollow long tube with one end connected to lateral surface of the tap body 2 having radial opening coaxial to the spout 14 and other end is open with outlet 15 for discharge of mixed water from the tap. The end cap 15 is inserted and fixed in end of the spout 14 as shown in the figure-1.

The tap body 2 is a hollow tube with two rings. The upper ring of the tap body 2 is having large inner diameter along with inner thread near top portion for fixing the tap cartridge 3 and one radial hole in its lateral surface with or without inner thread for connecting the spout 14. The tap body 2 acts as housing for the cartridge 3. The lower ring of the tap body 2 is having two concentric holes coaxially aligned to two concentric tubular valve seats 4a and 4b respectively. The inner valve seat 4a is coaxially extruded to connect to top end of the inner leg 8 via inner hole in the lower ring of the tap body 2 and the outer valve seat 4b is coaxial to the tubular outer leg 7 and extruded to touch upper surface of the lower ring of the tap body 2. The outer leg 7 is opened in the outer valve seat 4b. The lower ring also acts as a base for the main body A and along with the outer leg 7 is used for fixing the tap to the supporting surface of wash stand or bath stand or kitchen sink by using a nut Nl. Inner surfaces of these valve seats 4a and 4b are connected with inner surfaces of the inner leg 8 and the outer leg 7 respectively allowing water to enter in two concentric ports, inner port 3h and outer port 3g, in the bottom ceramic disc 2 of the cartridge 3 respectively. The outlet tubular spout 14 coaxial with the radial hole in the tap body 2 allowing mixed water to enter in the spout 14 before delivery through an outlet 15 in the spout 14 is connected to lateral surface of the body 2.

The inner leg 8 is concentric and inside the outer leg 7. The inner leg 8 and the outer leg 7 are connected to each other by four or three connecting plates 6 in radial direction. This arrangement of the tap body 2, the inner leg 8, the outer leg 7, the connecting plates 6 and the spout 14 is thought of, invented and developed to make it convenient to manufacture these parts of the main body A from probably a single mould die by moulding process or a single cast die by casting process using material like plastic, metal, glass or ceramic raw materials etc. in addition to its simple connection to surface of kitchen sink, washbasin, bathtubs etc. and economical in cost and easy to install and maintain. In addition the Taptee T is innovated for ease of connection of the main body A to hot and cold water supply lines separately. The tap body 2 can be made of metals or plastic or PVC or any other suitable solid material. These are innovative things which can not be found in the existing prior art water mixer taps.

There is one end cap 16 fixed at top end of the spout 14 so that mixed water should not pass through this end and discharge only through an opening/ outlet 15 in the spout 14.

The mono block ceramic discs tap cartridge 3 is shown in the Figure - 20. It is having the brass metal body 3a. It is not described in details, in that it is to be considered known and described in the field and can be seen in search engine like google.com by simply writing 'single/ mono block ceramic disc cartridge' in search box and clicking on search button. Only difference in the mono block disc cartridge 3 with the prior art is it has two concentric ports, inner port 3h and outer port 3g, in the fixed bottom ceramic disc K2 as shown in the figure 20(c) and 20(d) and two concentric retaining washers or O-ring Ra and Rb. The brass cartridge 3 is housed and fixed inside the tap body 2 by screwing it using threads 3i available in the brass type ceramic disc cartridge as shown in the figure - 20 and rotatably connected to a tap handle 1 by a screw. This tap cartridge 3 can be PVC/ plastic ceramic discs cartridge and can be housed and fixed inside the tap body 2 using a pull out nut. The type of cartridge can be any type available in the market with only main difference is concentric two ports in the lower fixed ceramic disc/ washer.

The two concentric retaining washers or O-rings Ra and Rb are fixed in the cartridge 3 and touches the inner valve seat 4a and the outer valve seat 4b respectively and acts as seal between the inner valve seat 4a and the outer valve seat 4b. These two washers or O-rings Ra and Rb stop any water leakage from one leg 7 to other leg 8 towards their top end edge and allow mixed water to outlet 15 when two concentric ports 3h and 3g are open due to rotation of the tap handle 1.

A securing washer Wl and a back nut Nl inserted in the outer leg 7 below base of the tap body 2 is to secure the main body A of the tap to supporting surface of a wash-stand like washbasin, kitchen sinks or bath tubs etc.

The main body A, attachable to the baths, kitchen sinks, washbasin etc., includes the tap body 2, the two concentric legs or tails, the inner leg or tail 8 and another the outer leg or tail 7, connected to each other near their top end by three or four rectangular plates 6 in radial direction or any other means, connected at bottom side of the tap body 2 and the spout 14 at the circumferential side. The main body A further includes mixing chamber 20 for mixing hot and cold water before passing the mixed water to outside of the tap via the spout 14 and then by the outlet 15. The amount of water discharged, and the hot and the cold water proportions of the water discharged, are both controlled by the tap handle 1 rotatably attached to the spindle 3f of the tap cartridge 3. The tap cartridge 3 is housed and fitted in the tap body 2 and having concentric ports/ holes in the bottom ceramic discs 2. The ceramic discs tap cartridge 3 is illustrated in the Figure-20. A hollow disc Zl and a washer W2 are inserted in the threaded end 9 of the inner leg 8 and stopped near round unthreaded outer surface of the leg 8. The inner leg 8 and the first leg 12 of the outer leg 7 are connected to the Taptee T. The two concentric legs 8 and 7 are inserted in the Taptee T such that the threaded end 9 of the inner leg 8 enters into a hole in the disc seat 9t and the female threaded end It screwed in the first leg 12 of the outer leg 7. The nut N3 is tighten to lock the Taptee T. The nut N2 is tighten in the threaded end 9 of the inner leg 8. The tightening of the nut N2 is done so that the washer W2 tightly touches the disc seat 9t in such a way that there should not be any water leakage, through the disc seat 9t in the outer leg 7.

The tubular first leg 2t and the tubular second leg 4t of the taptee T are for connection to hot water and cold water lines respectively. These legs 2t and 4t can be connected to hot and cold water lines separately either by female ends hose connector or to elbow or to tee joint or to any other pipe fittings as per requirement. The hose connectors used for connection may or may not be steel armoured. The hose connectors required in the prior art water mixer taps are steel armoured with one end is threaded male and other end is threaded female socket which are costlier and difficult to connect and remove.

The hot water enter the tap (FMT) through the inlet 8t of the first leg 2t and then to an inlet 10 of the inner leg 8 and then the outlet 11 in the inner leg 8 and then inner port 3h in the cartridge 3. The cold water enter the tap (FMT) through the inlet 3t of the second leg 4t and then to an inlet 13 in the first leg 12 of the outer leg 7 and then to an out let 5 of the outer leg 7 and then enter into the outer port 3g in the cartridge 3. If the tap handle 1 is turned manuall by user then the hot and cold water further flowed to a mixing chamber 20 before entering in the spout 14 and discharged through the outlet 15. When tap handle 1 rotates, upper ceramic disc (moving) Kl in the cartridge 3 also rotates and the two concentric ports/ holes 3h and 3g in the lower disc K2 opened and allow the hot and cold water to flow out of the cartridge 3 and mixed in the mixing chamber 20 and pass through the spout 14 and then the outlet 15. Hot water and cold water lines connections can be interchanged.

The amount and proportion of hot and cold water is controlled by rotation of the tap handle 1. When the tap handle 1 is turned in opposite direction then the water shuts off.

In this manner the tap handle 1 can be operated manually by a user, to allow delivery of the water and at the same time mixing of hot water and cold water.

In this embodiment in place of ceramic discs cartridge 3 other types of tap cartridges can also be used having concentric rubber washer or any other type of washers made of any other materials.

The spout 14 can be separately manufactured with additional features like inner thread socket near end of the tap body and screwed/ connected to additional features like threaded header in lateral surface with hole in the tap body 2. This is not disclosed but any person having common sense or knowledge can make it.

The spout 14 may not be integral part of the tap body 2 but can be received by making inner thread in the radial hole in the lateral surface of the tap body 2 coaxial to the tubular outlet spout 14 having threaded spigot with lower diameter than outer diameter of the spout 14 in some other embodiments which are not disclosed in this present invention.

This design makes the Fluid Mixer Taps (FMT) cost effective, easy to install and easy to maintain, robust in construction and ease of operation.

B. SECOND EMBODIMENT

The fluid mixer tap illustrated in Figure -2 mainly comprises the main body B and the Toupler C screwed in the main body B.

The main body B of the second embodiment is same as that of the main body A of the first embodiment with a little difference in the outer leg 7 and the spout 14. The outer leg T of the main body B is having the first leg 12 and the second leg 17. This second leg 17 is not a part of the outer leg 7 in the first embodiment of the Fluid Mixer Taps. The spout 14' of the main body B is different from the spout 14. In this embodiment no end cap 16, securing washer Wl and back nut Nl are required as they are there in the first embodiment.

The inner leg 8 in this second embodiment is same as that in the first embodiment of this invention Fluid Mixer Tap (FMT).

The outer leg 7' in this second embodiment is same as that in the first embodiment of this invention Fluid Mixer Tap (FMT) with an additional second leg 17. The outer leg 7' is a hollow tube having threaded first leg 12 near bottom end and threaded tubular leg 17 in radial direction for connection to cold water supply lines and upper end is connected to bottom of the lower ring of the tap body 2 similar to as in the first embodiment . The first leg 12 is for engaging the female threaded end lc of the Toupling C for the purpose of fixing and tightening the main body B to any suitable pipe fittings i.e. elbow or tee joints etc. of hot water supply line above washbasin, kitchen sinks, bath tubs etc. or in bathroom, washroom, industries etc. The second leg 17 is for connecting pipe fittings i.e. elbow or tee joints etc. or female ends hose connector of hot water supply line above washbasin, kitchen sinks, bath tubs etc. or in bathroom, washroom, industries etc. There is one hexagonal protrude 18 in the second leg 17 for assisting in tightening pipe fitting or female connector of a hose pipe.

The spout 14' is a hollow long tube with one end connected to the lateral surface of the tap body 2 having radial opening coaxial to the spout 14' and other end is open with the outlet 15' for discharge of mixed water from the tap as shown in the figure-2.

A hollow disc Zl and a washer W2 are inserted in the threaded end 9 of the inner leg 8 and stopped near round unthreaded outer surface of the leg 8. The inner leg 8 and the first leg 12 of the outer leg 7' are connected to the Toupling C by screwing in the female threaded end lc. The two concentric legs 8 and T are inserted in the Toupling C such that the threaded end 9 of the inner leg 8 enters into a hole in the disc seat 4c and the female threaded end lc screwed in the first leg 12 of the outer leg 7'. The nut N3 is tighten to lock the Toupling C. A nut N2 is tighten in the threaded end 9 of the inner leg 8. The tightening of the nut N2 is done so that the washer W2 tightly touches the disc seat 4c in such a way that there should not be any water leakage through the disc seat 4c into the outer leg 7'. The tubular first leg 2c of the Toupling C is for connection to hot water line and the second leg 17 of the outer leg T is for connection to the cold water line.

The hot water enter the tap through the inlet 3c of the first leg 2c and then to an inlet 10 of the inner leg 8 and then the outlet 11 in the inner leg 8 and then inner port 3h in the cartridge 3. The cold water enter the tap through the inlet 19 of the second leg 17 and then to an inlet 13' in the outer leg 7' and then to an out let 5 of the outer leg 7' and then enter into the outer port 3g in the cartridge. If the tap handle is turned manually by user then the hot and cold water further flow in to a mixing chamber 20 before entering in the spout 14' and discharged through the outlet 15'. When tap handle 1 rotates, upper ceramic disc (moving) l in the cartridge 3 also rotates and the two concentric ports/ holes 3h and 3g in the lower disc K2 opened and allow the hot and cold water flow out of the cartridge 3 to be mixed in a mixing chamber 20 and pass through the spout 14'.

The second embodiment may not be attachable to kitchen sinks, washbasin or bath tubs directly but can be fitted in the wall above the kitchen sink, washbasin, bathtubs etc. The amount and proportion of hot and cold water is controlled by the rotation of the tap handle 1. When the tap handle 1 is turned in opposite direction than the water shuts off.

In this embodiment in place of ceramic discs cartridge 3 other types of tap cartridges can also be used having concentric rubber washer or any other type of washers made of any other materials.

The spout 14' can be separately manufactured with additional features like inner thread socket near end of the tap body and screwed/ connected to additional features like threaded header in lateral surface in the tap body 2. This is not disclosed but any person having common sense or knowledge can make it.

In this manner the tap handle 1 can be operated manually by a user, to allow delivery of the water and at the same time mixing of hot water and cold water.

The spout 14' may not be integral part of the tap body 2 but can be received by making inner thread in the radial hole in the lateral surface of the tap body 2 coaxial to the tubular outlet spout 14' having threaded spigot with lower diameter than outer diameter of the spout 14' in some other embodiments which are not disclosed in this present invention.

This design makes the Fluid Mixer Taps (FMT) cost effective, easy to install and easy to maintain, robust in construction and easy in operation.

C. THIRD EMBODIMENT

Figure - 3 describes the Third Embodiment of the present invention Fluid Mixer Tap (FMT). Partly cross sectional and partly perspective view of the Third Embodiment of the present invention FMT is shown in Figure - 3.

Figure - 4 describes the main body D of the third embodiment of the present invention Fluid Mixer Tap (FMT). Partly cross sectional and partly perspective view of the main body D is shown in Figure - 3 and Figure-4.

The Fluid Mixer Tap (FMT) illustrated in Figure -3 substantially comprises the main body D and the Taptee T screwed in the main body D.

The main body D substantially comprises two tap bodies 2ax and 2ay, two tap cartridges 3ax and 3ay, two tap handles lax and lay, a header 13a, an interlocking mechanism, an outlet spout 12a and two concentric tubular legs inner leg 15a and outer leg 14a. The header 13a, the two concentric legs 15a and 14a are integral parts of the tap bodies 2ax and 2ay and can be moulded or casted in a single moulding die or casting die respectively making it cost effective and easy to manufacture commercially.

The main body D of the third embodiment is same as that of the main body A of the first embodiment with a difference in connectivity of concentric legs 14a and 15a with two valve seats 4ax and 4ay and two tap bodies 2ax and 2ay respectively, difference in ports in the cartridges 3ax and 3ay, difference in connectivity of the spout 12a with the header 13a and availability of the interlocking mechanism for hot water and cold water. Except the interlocking mechanism and two tap bodies and spindle-washer cartridge used in this embodiment there is not much difference in the first embodiment and the third embodiment of the present invention if think deeply.

The tap bodies 2ax and 2ay are hollow tubes extended at bottom end connected to the outer leg 14a, the inner leg 15a and the header 13a and the top end is having inner threads for fixing cartridges 3ax and 3ay inside the tap body 2ax and 2ay respectively as shown in the figure-3. The two valve seat tubes 4axt and 4ayt are an integral part of the tap bodies 2ax and 2ay respectively and also extruded to the outer leg 14a and the inner leg 15a respectively at bottom end and connected to the valve seats 4ax and 4ay respectively at top end. The upper part of the tap bodies 2ax and 2ay are having large inner diameter along with inner threads near top end portion for fixing the tap cartridges 3ax and 3ay respectively. Their lower portion is curved and designed such that the valve seat tubes 4axt and 4ayt protrude inside them. The tap bodies 2ax and 2ay extruded to the inner leg 15a and the outer leg 14a respectively, extruded to the header 13a and also they are connected to each other as shown in the figure - 3 and figure - 4. There is one outlet opening 6ax and 6ay towards the header 13a in the tap bodies 2ax and 2ay respectively for allowing water to enter in the header 13a. The tap bodies 2ax and 2ay act as housing for the cartridges 3ax and 3ay respectively. The hollow valve seat tube 4axt at its bottom end protrudes in the tap body 2ax is also connected to upper end of the outer leg 14a for allowing water to enter in the valve seat 4ax via the outer leg 14a. The hollow valve seat tube 4ayt at its bottom end protrudes in the tap body 2ay is also connected to upper end of the inner leg 15a for allowing water to enter in the valve seat 4ay via the inner leg 15a. A protrude 27a in the outer leg 14a acts as a base for the main body D and along with the outer leg 14a it is used for fixing on supporting surface of a wash stand or bath stand or kitchen sink or any other such surface by using and tightening a nut Nl. Inner surfaces of these valve seat tubes 4axt and 4ayt are matching with inner surfaces of the inner leg 15a and the outer leg 14a respectively and the inner surfaces of the valve seats 4ax and 4ay respectively and allows water to enter in the mixer chamber 7a through the interlocking mechanism through the outlet 6ax of the tap body 2ax and the outlet 6ay of the tap body 2ay when tap handles lax and lay are turned for lifting up the cartridges 3ax and 3ay respectively allowing cold and hot water to enter in the interlocking mechanism respectively. The outlet tubular spout 12a bottom end is coaxial with an opening in the header 13a and screwed in the threaded end 21a in top end of the header 13a for allowing mixed water to enter in the spout 12a before delivery through an aerator al fitted in outlet in the spout 15a.

The inner leg 15a is a hollow tube with plain outer surface except threaded end 17a near its bottom end and bent near its top end extruded to connect to the valve seat tube 4ayt, the tap bodies 2ax and 2ay and to top end of the outer leg 14a. The outer diameter of the plain surface of the inner leg 15a is more than the outer diameter of the threaded end 17a of the inner leg 15a.

The outer leg 14a is a hollow tube having threaded outer surface for engaging the nut Nl for the purpose of fixing and tightening the main body D near the protrude 27a to the surface of washbasin, kitchen sinks, bath tubs or any other such surface by screwing and tightening the nut Nl. The top end of the outer leg 14a is extruded to the tap bodies 2ax and 2ay, the valve seat 4axt and top end of the inner leg 15a.

The spout 12a is a hollow long bent tube with one bottom socket end having inner thread and top end is connected to the aerator al. The spout 12a with aerator al is same as any other similar spout available in the market. The socket bottom end is connected to the header 13a by screwing in the threaded end 21a of the header 13a.

The inner leg 15a is concentric to the outer leg 14a for most portion of their length. The inner leg 15a is inside the outer leg 14a. Top end of both the legs 15a and 14a are bent and extended to connect to the valve seat 4ay and 4ax via the valve seat tubes 4ayt and 4axt respectively as shown in the figure-3. The protrude 27a in the outer surface of the outer leg 14a is used as base for the main body D for fitting on surface of kitchen sinks, washbasin, bathtubs etc. by the securing washer Wl and the nut Nl. The inner leg 15a and the outer leg 14a are connected to each other and to the tap bodies 2ax and 2ay in such a way that they allow independently flow of cold and hot water to be mixed in the mixing chamber 7a when the tap handle lay and then lax are turned. This arrangement of the tap bodies 2ax and 2ay, the inner leg 15a, the outer leg 14a and the header 13a is thought of, invented and developed to make it convenient to manufacture these parts of the main body D from probably a single mould die by moulding process or a single cast die by casting process using material like plastic, metal, glass or ceramic raw materials etc. In addition the taptee T is innovated for ease of connection of the main body D to hot and cold water supply lines separately. The tap bodies 2ax and 2ay can be made of metals or plastic or PVC or any other suitable solid material. These are innovative things which can not be found in the existing prior art water mixer taps.

The spindle-washer tap cartridge or ceramic discs tap cartridge 3ax and 3ay are not described in details, in that it is to be considered known and described in the field and can be seen in search engine like google.com by simply writing 'spindle-washer tap cartridge or ceramic disc tap cartridge' in search box and clicking on search button. Two washers W3 each are connected to the cartridges 3ax and 3ay sit on valve seats 4ax and 4ay of the tap bodies 2ax and 2ay respectively when the tap is shuts off.

The tap bodies 2ax and 2ay of the main body D, attachable to the baths, kitchen sinks, washbasin etc., includes the two concentric legs or tails, the inner leg or tail 15a and the outer leg or tail 14a, the interlocking mechanism and the header 13a. The two concentric legs 14a and 15a are connected to each other at their top ends as well as to the tap bodies 2ax and 2ay as shown in the figure - 3. The tap bodies 2ax and 2ay further include mixing chamber 7a in the header 13a for mixing hot and cold water before passing the mixed water to outside of the tap via the spout 13a, a partition wall 20a between outlets 6ax and 6ay for allowing hot and cold water in the mixing chamber 7a through the interlocking mechanism. The amount of water discharged, and the hot and the cold water proportions of the water discharged, are both controlled by two tap handles lax and lay rotatably attached to the spindle of the tap cartridges 3ax and the 3ay respectively. The tap cartridges 3ax and 3ay are housed and fitted in the tap bodies 2ax and 2ay respectively. The inner leg 15a and the first leg 18a of the outer leg 14a are connected to the Taptee T. The hollow disc Zl and the washer W2 are inserted in the threaded end 17a of the inner leg 15a and stopped near round unthreaded outer surface of the leg 15a. The two concentric legs 15a and 14a are inserted in the Taptee T i.e. the Taptee T is screwed in the main body D such that the threaded end 17a of the inner leg 15a enters into a hole in the disc seat 9t and the female threaded end It screwed in the first leg 18a of the outer leg 14a. The nut N3 is tighten to lock the Taptee T. A nut N2 is tighten in the threaded end 17a of the inner leg 15a. The tightening of the nut N2 is done so that the washer W2 tightly touches the disc seat 9t in such a way that there should not be any water leakage through the disc seat 9t in the outer leg 14a.

The tubular first leg 2t and the tubular second leg 4t of the taptee T are for connection to cold water and hot water lines respectively as described in the first embodiment of this invention.

The interlocking mechanism comprises the header 13a extruded at its bottom to the tap bodies 2ax and 2ay, the header disc 8a, the stopper Ml, the header disc seat body LI, the partition wall 20a and grooves 9a, 10a and 11a in the header 13a . The partition wall 20a separates two tap bodies 2ax and 2ay and is for keeping hot and cold water separately before entering in the mixing chamber 7a through the interlocking mechanism. The header disc 8a with its heavier surface side due to additional weight 8ab is kept towards cold water line and other end towards hot water line. The two cylindrical protrudes 8aa are inserted in the two opposite grooves 11a and two sides of the disc 8ac rotates about an axis of the two protrudes 8aa. The stoppers Ml with its curved surface Mia towards bottom side facing the curved face of the protrudes 8aa are inserted in the two opposite grooves lla from top and are fixed to allow the disc 8ac to rotate about the protrudes' 8aa axis. The additional weight 8ab is for keeping heavier side in downward direction to ensure touching of opposite upper end to the disc seat Lib. The header disc seat body LI with the disc seat Lib, facing and touching upper face of the disc 8ac, is inserted in the three grooves one 9a and other two opposite grooves 10a by using the three protrudes Lla. The body LI is fixed in the header 13a towards hot water line at a location where one side of the disc 8ac touches the seat Lib due to gravitational force due to additional weight 8ab which try to pull this side of the disc in downward direction. The touching of the disc 8ac with the seat Lib does not allow hot water to enter into the mixing chamber 7a until the tap handle lay is turned to allow delivery of cold water from the inner leg 15a into outlet 6ay thereby lifting/ pushing half portion of the disc 8ac in upward direction causing downward motion for the portion of the disc 8ac in hot water line direction due to rotation of the disc about the protrudes 8aa axis resulting into opening of the disc seat Lib allowing hot water to enter in the mixer chamber 7a if the tap handle lax is turned. This interlocking will not allow the hot water to enter in the mixer chamber 7a until the cold water tap handle lay is turned there by lifting the washer W3 and allowing cold water to enter in the mixer chamber first. If there is no cold water and only hot water is available in the hot water line then even after opening of valve seat 4ay by turning the tap handle lay the disc seat Lib will not open since the disc 8ac will remain touching it there by obstructing flow of hot water in the mixer chamber 7a through the inner opening [Lid) in the body LI and hence no water will be delivered by the spout 12a through the aerator al. When the tap handle lay turned in one direction cold water enters the interlocking mechanism rotating the disc 8ac making opening in this side of the header as well as on the opposite side of it and when the tap handle lax is turned the hot water enters the mixing chamber 7a and then mixed water flows out of the spout 12a through the aerator al. This interlocking will protect users from scalding injuries and thermal shock. Such interlocking mechanism are not there in prior art.

The connection of the main body D to the Taptee T is same as that in the first embodiment and is not explained here. The first leg 2t is connected to the cold water line and the second leg 4t is connected to the hot water line using either hose pipes or any other suitable pipe fittings.

The cold water enter the tap through the inlet 8t of the first leg 2t and then to an inlet 16a of the inner leg 15a and then the outlet 5ay in the inner leg 15a and then the valve seat 4ay and if the tap handle lay is turned manually by user then the washer W3 is lifted up and cold water further flowed to the outlet 6ay, then the cold water push and rotate the disc 8ac thereby allowing cold water to enter in the mixing chamber 7a before entering in the spout 12a. The hot water enter the tap through the inlet 3t of the second leg 4t and then to an inlet 19a in the first leg 18a of the outer leg 14a and then to an out let 5ax of the outer leg 14ax and then enter into the valve seat 4ax in the tap body 2ax and if the tap handle is turned manually by user then the hot water further flowed to outlet 6ax and will enter the mixing chamber 7a only when the disc 8ac is in downward direction allowing flow of hot water to the mixing chamber 7a before entering in the spout 12a and then mixed water discharged through the spout 12a and the aerator al.

The amount and proportion of hot and cold water is controlled by rotation of the tap handles lax and lay. When the tap handles lax and lay are turned in opposite direction then the water shuts off.

In this manner the tap handles lax and lay can be operated manually by a user, to allow delivery of the water and the mixing of hot water and cold water. In this embodiment in place of spindle-washer cartridges 3ax and 3ay other types of tap cartridges can also be used.

This design makes the Fluid Mixer Tap or Valve (FMT) cost effective, easy to install, easy to maintain, robust in construction and ease of operation.

D. FOURTH EMBODIMENT

Figure - 5 describes the main body E of the Fourth Embodiment of the present invention Fluid Mixer Tap (FMT). Partly cross sectional and partly perspective view of the main body of the Fourth Embodiment of the present invention is shown in Figure - 5.

The Fluid Mixer Tap (FMT) in the Fourth Embodiment mainly comprises a main body E and the Taptee T. In Figure - 5, only the main body E is shown. The Taptee T is connected to the main body E in the same way as it is to the main body D in the third embodiment.

The main body E of the fourth embodiment is same as that of the main body D of the third embodiment without the interlocking mechanism in the header 13a' as shown in the figure-5. Here the header 13a' is connected to the tap bodies 2ax and 2ay having threaded upper end for screwing in the spout 12a. In the header 13a' there are no grooves 9a, 10a, 11a, no header disc 8a, no stopper Ml, no header disc body LI and no partition wall 20a. When both tap handle lax and lay are open then hot and cold water directly reaches the mixer chamber 7a' through the outlet 6ax and 6ay.

The connection of the main body E to the Taptee T is same as that in the third embodiment and is not explained here. The first leg 2t is connected to the cold water supply line and the second leg 4t is connected to the hot water supply line using either hose pipes or any other suitable pipe fittings. Here connections are interchangeable.

The cold water enter the tap through the inlet 8t of the first leg 2t and then to an inlet 16a of the inner leg 15a and then the outlet 5ay in the inner leg 15a and then the valve seat 4ay and if the tap handle lay is turned manually by user then the washer W3 lifted up and cold water further flowed to the outlet 6ay after that reaches the mixing chamber 7a' before entering in the spout 12a. The hot water enter the tap through the inlet 3t of the second leg 4t and then to an inlet 19a in the first leg 18a of the outer leg 14a and then to an out let 5ax of the outer leg 14a and then enter into the valve seat 4ax in the tap body 2ax and if the tap handle lax is turned manually by user then the cold water further flowed to outlet 6ax and after that enter the mixing chamber 7a' before entering in the spout 12a and then mixed water discharged through the spout 12a and the aerator al.

The amount and proportion of hot and cold water is controlled by the rotation of the tap handles lax and lay. When the tap handles lax and lay are turned in opposite direction then the water shuts off.

In this manner the tap handles lax and lay can be operated manually by a user, to allow delivery of the water and the mixing of hot water and cold water.

In this embodiment in place of spindle-washer cartridges 3ax and 3ay other types of tap cartridges can also be used.

This design makes the Fluid Mixer Taps (FMT) cost effective, easy to install and easy to maintain, robust in construction and easy in operation. E. FIFTH EMBODIMENT

Top end of the outer leg 7b is supported and connected to bottom surface of the lower ring of the tap body 2b and coaxial to the inner hollow tubular cut in the lower portion of the upper ring of the tap body 2b as per figure-8. This arrangement of the tap body 2b, the inner leg 6b, the outer leg 7b, the connecting plate 24b and the spout 13b is thought of and developed to make it convenient to manufacture these parts of the main body A' from probably a single mould die by moulding process or a single cast die by casting process using material like plastic, metal, glass or ceramic raw materials etc. In addition the taptee T is innovated for ease of connection of the main body A' to hot and cold water supply lines separately. The tap body 2b can be made of metals or plastic or PVC or any other suitable solid material. These are innovative things which can not be found in the existing prior art water mixer taps.

There is one end cap 17b fixed at top end of the spout 13b so that mixed water should not pass through this end and discharge only through an opening/ outlet 16b in the spout 13b.

The spindle-washer tap cartridge or ceramic discs tap cartridge 3b is not described in details, in that it is to be considered known and described in the field and can be seen in search engine like google.com by simply writing 'spindle-washer tap cartridge or ceramic disc tap cartridge' in search box and clicking on search button. One washer W3 is connected to the cartridge 3b sit on valve seats 4b of the tap body 2b.

In the outer leg 7b below base of the tap body 2b, a securing washer Wl and a back nut Nl acts to secure the main body A' of the tap to a supporting surface of a wash-stand like washbasin, kitchen sinks or bath tubs etc. The main body A', attachable to the baths, kitchen sinks, washbasin etc., includes the tap body 2, the two concentric legs or tails, one inner leg or tail 6b whose top end connected to the tap body 2b by the circular hollow connecting plate 24b and another outer leg or tail 7b connected to bottom ring of the tap body 2b and the spout 13b connected at the lateral surface of the tap body 2b. The spout 13b further includes mixing chamber/ outlet 16b for mixing the hot and the cold water before passing the mixed water to outside of the tap via the outlet 16b. The amount of hot water discharged is controlled by the tap handle lb rotatably attached to spindle of the tap cartridge 3b. The tap cartridge 3b is housed and fitted in the tap body 2b having the washer W3 fixed in the bottom. The amount of cold water is controlled by a separate tap (not shown in the figure -8) connected to the second leg 4t using hose pipe or any other suitable pipe fittings. A hollow disc Zl and a washer W2 are inserted in the threaded end 10b of the inner leg 6b and stopped near round unthreaded outer surface of the leg 6b. The inner leg 6b and the first leg 12b of the outer leg 7b are connected to the Taptee T. The two concentric legs are inserted in the Taptee T such that the threaded end 10b of the inner leg 6b enters into a hole in the disc seat 9t and the female threaded end It screwed in the first leg 12b of the outer leg 7b. The nut N3 is tighten to lock the Taptee T. The nut N2 is tighten in the threaded end 10b of the inner leg 6b. The tightening of the nut N2 is done so that the washer W2 tightly touches the disc seat 9t in such a way that there should not be any water leakage through the disc seat 9t.

The tubular first leg 2t and the tubular second leg 4t of the taptee T are for connection to hot water and cold water lines respectively. These legs 2t and 4t can be connected to hot and cold water lines separately either by female ends hose connector or elbow or tee joint or any other pipe fittings as per requirement. The second leg 4t is connected to a water tap by a female hose connector or any other suitable pipe fittings. The water tap is connected to the cold water line. The hose connectors used for connection may or may not be steel armoured. The hose connectors required in the existing water mixer taps are steel armoured with one end is threaded male and other end is threaded female socket which are costlier.

The hot water enter the tap through the inlet 8t of. the first leg 2t and then to an inlet 9b of the inner leg 6b and then the outlet 5b in the inner leg 6b and then the washer W3 in the cartridge 3b and if the tap handle lb is turned manually by user then the hot water further flowed to a mixing chamber/outlet 16b after the spout 13b. When tap handle lb rotates, the washer W3 lifted up and then open the valve seat 4b and allow hot water out of the tap body 2b to be mixed in the mixing chamber 16b after passing through the upper chamber 14b. The cold water enter the tap body 2b through the inlet 3t of the second leg 4t and then to a inlet lib in the first leg 12b of the outer leg 7b and then to an out let 8b of the outer leg 7b and then enter into the lower chamber 15b in the spout 13b and then the hot water further flowed to a mixing chamber 16b and then discharged. The flow of hot water is controlled by the external tap connected to the second leg 4t. The hot water and cold water lines connections can be interchanged. In some uses there may be one type of water or one source of water feeding both inlets.

The amount and proportion of hot and cold water is controlled by the rotation of the tap handle lb and opening/ closing of the external tap handle. When the tap handle lb is turned in opposite direction than the hot water shuts off.

In this embodiment in place of spindle-washer cartridges 3b other types of tap cartridges can also be used.

The spout 13b can be separately manufactured with additional features like inner thread socket near end of the tap body 2b and ; screwed/ connected to additional features like threaded header in lateral surface in the tap body 2b. This is not disclosed but any person having common sense or knowledge can make it. *

This 8 ^th embodiment may not be attachable to kitchen sinks, washbasin or bath tubs directly. It can also be fitted to shower.

The cold water enter the tap through the inlet 3c of the first leg 2c and then to an inlet 16d of the inner leg 15d and then the outlet 5dx in the inner leg 13d before entering the valve seat 4dx and if the tap handle ldx is turned manually by user then the cold water further flowed to a mixing chamber 7d through the outlet 6dx before entering in the header 9d. The hot water enter the tap through an inlet 20d of the second leg 19d and then to an inlet 21d in the outer leg 12d and then to an out let 5dy of the outer leg 12d and enter the valve seat 4dy and if the tap handle ldy is turned manually by user then the hot water further flowed to a mixing chamber 7d through the outlet 6dy before entering in the header 9d. When both tap handles ldx and ldy are turned then the mixed water flows out of the outlet lid. The hot water and cold water lines connections can be interchanged.

The amount and proportion of the cold and the hot water is controlled by the rotation of the tap handles ldx and ldy. When the tap handles ldx and ldy are turned in opposite direction than the water shuts off.

In this manner the tap handles ldx and ldy can be operated manually by a user, to allow delivery of the water and the mixing of hot water and cold water.

In this embodiment in place of spindle-washer cartridges 3dx and 3dy other types of tap cartridges can also be used.

This design makes the Fluid Mixer Taps or Valves (FMT) cost effective, easy to install and easy to maintain, robust in construction and easy of operation.

K. ELENTH EMBODIMENT

Figure - 15 describes the Eleventh Embodiment of the present invention Fluid Mixer Tap (FMT). Partly cross sectional and partly perspective view of the eleventh embodiment of the present invention is shown in Figure - 15.

The Fluid Mixer Tap illustrated in Figure -15 comprises only the main body A" and no Toupling C or Taptee T required for connection to cold and hot water lines.

The main body A" of the eleventh embodiment is same as that of the main body A of the first embodiment except one additional threaded hollow female socket 9" extruded in radial direction from the inner leg 8" and then a cut in the outer leg or tail 7" as shown in the figure -15.

The tap body 2, the tap handle 1, the spout 14, the cartridge 3, the inner ring Ra, the outer ring Rb, the inner valve seat 4a, the outer valve seat 4b, the mixing chamber 20, the nut Nl and the washer Wl are same as that in the first embodiment of the present invention. The only difference in the first and eleventh embodiment is in the outer leg 7 and the inner leg 8 and the spout 14 of the first embodiment.

The main body A" substantially comprises the tap body 2, the tap handle 1, the tap cartridge 3, the outlet spout 14 and the two concentric tubular legs or tails named inner leg 8" and outer leg 7". The spout 14 and the two concentric legs 7" and 8" connected by the plates 6" are an integral part of the tap body 2 and can be moulded or casted in a single moulding die or casting die.

The inner leg 8" is a hollow tube with plain outer surface bent near its bottom end and opened through the outer leg 7" in radial direction for connection to hot water supply line as shown in the figure-15.

The outer leg 7" is a hollow tube having threaded outer surface for engaging the nut Nl for the purpose of fixing and tightening the main body A" to a surface of washbasin, kitchen sinks, bath tubs or any other surface by screwing the nut Nl. There is one hole near its bottom in radial direction for the second leg 9 for connection to hot water supply line.

Top diametrical surface of both the legs 8" and 7" are extruded to connect to the valve seat 4a and 4b respectively.

The spout 14 is a hollow long tube with one end connected to the lateral surface of the tap body 2 having radial opening coaxial to the spout 14 and other end is open with outlet 15 for discharge of mixed water from the tap. The end cap 15 is inserted and fixed in the end of the spout 14 as shown in the figure-15.

The tap body 2 is a hollow tube with two rings. The upper ring of the tap body 2 is having large inner diameter along with inner thread near top portion for fixing the tap cartridge 3 and one radial hole in its lateral surface with or without inner thread for connecting the spout 14. The tap body 2 acts as housing for the cartridge 3. The lower ring of the tap body 2 is having two concentric holes coaxially aligned to two concentric tubular valve seats 4a and 4b respectively. The inner valve seat 4a is coaxially extruded to connect to top end of the inner leg 8" via inner hole in the lower ring of the tap body 2 and the outer valve seat 4b is coaxial to the tubular outer leg 7" and extruded to touch upper surface of the lower ring of the tap body 2. The outer leg 7" is opened in the outer valve seat 4b. The lower ring also acts as a base for the main body A" and along with the outer leg 7" is used for fixing the tap to the supporting surface of wash stand or bath stand or kitchen sink by using a nut Nl. Inner surfaces of these valve seats 4a and 4b are connected with inner surfaces of the inner leg 8" and the outer leg 7" respectively allowing water to enter in two concentric ports, inner port 3h and outer port 3g, in the bottom ceramic disc K2 of the cartridge 3 respectively. The outlet tubular spout 14 coaxial with the radial hole in the tap body 2 allowing mixed water to enter in the spout 14 before delivery through the outlet 15 in the spout 14 is connected to lateral surface of the body 2.

The inner leg 8" is a hollow tube concentric and inside the outer leg 7" with bottom end bent in radial direction connecting to the outer leg 7" in radial direction with inner threaded end female socket named second leg 9" for connection to hot water supply line. The inner leg 8" and the outer leg 7" are connected to each other by four or three connecting plates 6" in radial direction. This arrangement of the tap body 2, the inner leg 8", the outer leg 7", the connecting plates 6", the second leg 9" and the spout 14 is thought of, invented and developed to make it convenient to manufacture these parts of the main body A" from probably a single mould die by moulding process or a single cast die by casting process using material like plastic, metal, glass or ceramic raw materials etc. in addition to its simple connection to surface of kitchen sink, washbasin, bathtubs etc. and economical in cost and easy to install and maintain. In addition the female socket second leg 9" is innovated for ease of connection of the main body A" to hot water supply line. The tap body 2 can be made of metals or plastic or PVC or any other suitable solid material. These are innovative things which can not be found in the existing prior art water mixer taps.

There is one end cap 16 fixed at top end of the spout 14 so that mixed water should not pass through this end and discharge only through an opening/ outlet 15 in the spout 14.

The mono block ceramic discs tap cartridge 3 is shown in the Figure - 20. It is same as that explained in the first embodiment and hence not explained in here.

The two concentric retaining washers or O-rings Ra and Rb are fixed in the cartridge 3 and touches the inner valve seat 4a and the outer valve seat 4b respectively and acts as seal between the inner valve seat 4a and the outer valve seat 4b. These two washers or O-rings Ra and Rb stop any water leakage from one leg 7" to other leg 8" towards their top end edge and allow mixed water to outlet 15 when two concentric ports 3h and 3g are open due to rotation of the tap handle 1.

A securing washer Wl and a back nut Nl inserted in the outer leg 7" below base of the tap body 2 is to secure the main body A" of the tap to supporting surface of a wash-stand like washbasin, kitchen sinks or bath tubs etc.

The main body A", attachable to the baths, kitchen sinks, washbasin etc., includes the tap body 2, the two concentric legs or tails, the inner leg or tail 8" bent at its bottom end connected to the outer leg 7" in radial direction and the outer leg or tail 7", connected to each other near their top end by three or four rectangular plates 6" in radial direction or any other means 6", connected at bottom side of the tap body 2 and the spout 14 at the circumferential side. The main body A" further includes mixing chamber 20 for mixing hot and cold water before passing the mixed water to outside of the tap via the spout 14 and then by the outlet 15. The amount of water discharged, and the hot and the cold water proportions of the water discharged, are both controlled by the tap handle 1 rotatably attached to the spindle 3f of the tap cartridge 3. The tap cartridge 3 is housed and fitted in the tap body 2 having concentric ports/ holes in the bottom ceramic discs 2. The ceramic discs tap cartridge 3 is illustrated in the Figure-20. The first leg 12" in the outer leg 7" is for connection to cold water supply line through female hose connector or any other suitable pipe fittings like elbow, tee joints etc. where as the second leg 9" is for connection to hot water line through male-female hose connector or through any suitable pipe fittings like nipple, elbow or tee joints etc.

The hot water enter the tap (FMT) through the inlet 10" of the second leg 9" and then the outlet 11" in the inner leg 8" and then inner port 3h in the cartridge 3 and if the tap handle 1 is turned manually by user then the hot water further flowed to the mixing chamber 20 before entering in the spout 14. The cold water enter the tap through the inlet 13" of the first leg 12" and then to an out let 5" of the outer leg 7" and then enter into the outer port 3g in the cartridge 3 and if the tap handle 1 is turned manually by user then the cold water further flowed to the mixing chamber 20 before entering in the spout 14 and discharged through the outlet 15. When the tap handle 1 rotates, upper ceramic disc (moving) Kl in the cartridge 3 also rotates and the two concentric ports/ holes 3h and 3g in the lower disc K2 opened and allow hot and cold water flow out of the cartridge 3 to be mixed in the mixing chamber 20 and discharged through the spout 14. Hot water and cold water lines connections can be interchanged.

The amount and proportion of hot and cold water is controlled by rotation of the tap handle 1. When the tap handle 1 is turned in opposite direction than the water shuts off.

In this manner the tap handle 1 can be operated manually by a user, to allow delivery of the water and at the same time mixing of hot water and cold water.

In this embodiment in place of ceramic discs cartridge 3 other types of tap cartridges can also be used having concentric rubber washer or any other type of washers or made of any other materials.

The spout 14 can be separately manufactured with additional features like inner thread socket near end of the tap body and screwed/ connected to additional features like threaded header in lateral surface in the tap body 2. This is not disclosed but any person having common sense or knowledge can make it.

The spout 14 may not be integral part of the tap body 2 but can be received by making inner thread in the radial hole in the lateral surface of the tap body 2 coaxial to the tubular outlet spout 14 having threaded spigot with lower diameter than outer diameter of the spout 14 in some other embodiments which are not disclosed in this present invention.

This design makes the Fluid Mixer Taps (FMT) cost effective, easy to install and easy to maintain, robust in construction and ease of operation.

The inner leg 8"' is a hollow tube with plain outer surface bent near its bottom end and opened through the outer leg T" in radial direction and connected to the second leg 9"' for connection to hot water supply line as shown in the figure- 16.

The outer leg T" is a hollow tube having plain outer surface bent at its bottom and connected to the first leg 12"'. The first leg 12"' is a hollow tube having threaded outer surface with one hexagonal edge 19"' is for connection to cold water supply line. The other end of the first leg 12"' is connected to the outer leg T" in radial direction and opened in it for flow of water/ fluids inside the outer leg 7"'. There is one hole near its bottom in radial direction for the second leg 9"' for connection to hot water supply line.

Top diametrical surface of both the legs 8" and 7" are extruded to connect to the valve seat 4a and 4b respectively.

The header 14"' is a hollow long tube with one end connected to the lateral surface of the tap body 2 having radial opening coaxial to the header 14"' and other end is open with threaded outlet 16"' for discharge of mixed water from the tap. There is one hexagonal protrudes 17"' in the header 14"'.

The tap body 2 is a hollow tube with two rings. The upper ring of the tap body 2 is having large inner diameter along with inner thread near top portion for fixing the tap cartridge 3 and one radial hole in its lateral surface with or without inner thread for connecting the header 14"'. The tap body 2 acts as housing for the cartridge 3. The lower ring of the tap body 2 is having two concentric holes coaxially aligned to two concentric tubular valve seats 4a and 4b respectively. The inner valve seat 4a is coaxially extruded to connect to top end of the inner leg 8"' via inner hole in the lower ring of the tap body 2 and the outer valve seat 4b is coaxial to the tubular outer leg 7"' and extruded to touch upper surface of the lower ring of the tap body 2. The outer leg 7"' is opened in the outer valve seat 4b. Inner surfaces of these valve seats 4a and 4b are connected with inner surfaces of the inner leg 8" and the outer leg 7" respectively allowing water to enter in two concentric ports, inner port 3h and outer port 3g, in the bottom ceramic disc K2 of the cartridge 3 respectively. The outlet tubular header 14"' coaxial with the radial hole in the tap body 2 allowing mixed water to enter in the heade 14"' before delivery through the outlet 16"' in the header 14"' is connected to lateral surface of the body 2.

The inner leg 8"' is a hollow tube concentric and inside the outer leg 7"' with bottom end bent in radial direction connecting to the second threaded leg 9"' through a hole in the outer leg T" in radial direction for connection to hot water supply line. The inner leg 8"' and the outer leg 7"' are connected to each other by four or three connecting plates 6"' in radial direction. This arrangement of the tap body 2, the inner leg 8"', the outer leg 7"', the connecting plates 6"', the second leg 9"', the first leg 12"' and the header 14"' is thought of, invented and developed to make it convenient to manufacture these parts of the main body A'" from probably a single mould die by moulding process or a single cast die by casting process using material like plastic, metal, glass or ceramic raw materials etc. The tap body 2 can be made of metals or plastic or PVC or any other suitable solid material. These are innovative things which can not be found in the existing prior art water mixer taps.

The mono block ceramic discs tap cartridge 3 is shown in the Figure - 20. It is same as that explained in the first embodiment and hence not explained in here.

The two concentric retaining washers or O-rings Ra and Rb are fixed in the cartridge 3 and touches the inner valve seat 4a and the outer valve seat 4b respectively and acts as seal between the inner valve seat 4a and the outer valve seat 4b. These two washers or O-rings Ra and Rb stop any water leakage from one leg 7"' to other leg 8"' towards their top end edge and allow mixed water to outlet 16 when two concentric ports 3h and 3g are open due to rotation of the tap handle 1.

The main body A'", attachable to pipe system, includes the tap body 2, the two concentric legs or tails, the inner leg or tail 8"' bent at its bottom end connected to the second leg 9"' through the hole in the outer leg 7" in radial direction and the outer leg or tail 7" bent at its bottom end and connected to the first leg 12'", connected to each other near their top end by three or four rectangular plates 6"' in radial direction or any other means 6"', connected at bottom side of the tap body 2 and the outlet header 14"' at the circumferential side. The main body A'" further includes mixing chamber 20 for mixing hot and cold water before passing mixed water to outside of the tap via the header 14"' and then by the outlet 16"'. The amount of water discharged, and the hot and the cold water proportions of the water discharged, are both controlled by the tap handle 1 rotatably attached to the spindle 3f of the tap cartridge 3. The tap cartridge 3 is housed and fitted in the tap body 2 having concentric ports/ holes in the bottom ceramic discs K2. The ceramic discs tap cartridge 3 is illustrated in the Figure-20. The first leg 12"' in the outer leg 7"' is for connection to cold water supply line through female hose connector or any other suitable pipe fittings like elbow, tee joints etc. where as the second leg 9"' is for connection to hot water line through female-female hose connector or through any suitable pipe fittings like nipple, elbow or tee joints etc.

The hot water enter the tap (FMT) through the inlet 10"' of the second leg 9"' and then the outlet 11"' in the inner leg 8"' and then inner port 3h in the cartridge 3 and if the tap handle 1 is turned manually by user then the hot water further flowed to the mixing chamber 20 before entering in the header 14"'. The cold water enter the tap through the inlet 13"' of the first leg 12"' and then to an out let 5"' of the outer leg 7"' and then enter into the outer port 3g in the cartridge 3 and if the tap handle 1 is turned manually by user then the cold water further flowed to the mixing chamber 20 before entering in the header 14 and discharged through the outlet 15"' in the outlet header 16"'. When the tap handle 1 rotates, upper ceramic disc (moving) Kl in the cartridge 3 also rotates and the two concentric ports/ holes 3h and 3g in the lower disc K2 opened and allow hot and cold water flow out of the cartridge 3 to be mixed in the mixing chamber 20 and discharged through the header 14"'. Hot water and cold water lines connections can be interchanged.

The amount and proportion of hot and cold water is controlled by rotation of the tap handle 1. When the tap handle 1 is turned in opposite direction than the water shuts off.

In this manner the tap handle 1 can be operated manually by a user, to allow delivery of the water and at the same time mixing of hot water and cold water.

In this embodiment in place of ceramic discs cartridge 3 other types of tap cartridges can also be used having concentric rubber washer or any other type of washers or made of any other materials. The header 14"' can be separately manufactured with additional features like inner thread socket near end of the tap body and screwed/ connected to additional features like threaded header in lateral surface in the tap body 2. This is not disclosed but any person having common sense or knowledge can make it.

The header 14"' may not be integral part of the tap body 2 but can be received by making inner thread in the radial hole in the lateral surface of the tap body 2 coaxial to the tubular outlet header 14"' having threaded spigot with lower diameter than outer diameter of the header 14 in some other embodiments which are not disclosed in this present invention.

This design makes the Fluid Mixer Taps (FMT) cost effective, easy to install and easy to maintain, robust in construction and ease of operation.
