容積形機械
Document Type and Number:
Japanese Patent JP4042417
Kind Code:
B2
Abstract:
Positive displacement machine that has a limb that oscillates with reciprocating motion. Using the oscillating movement, the connection between the working chamber and the suction pressure space or the discharge pressure chamber is changed. In this machine you can only decrease the diameter of the piston in relation to the size of each sliding section. By improving the productivity and reliability of said machine it is possible to make a compressor that can withstand the use of a very high pressure refrigerant, such as carbon dioxide, thereby further improving the efficiency of the entire refrigeration cycle system of the invention It is useful for simplifying the valve mechanism on the positive displacement machine, improving reliability relative to the use of a high pressure working fluid, and reducing the loss of mechanical friction.
