Japanese Patent JP7449593
Kind Code:
B2
Abstract:
To provide a liquid pressure feed device improved in operation of valves by an operation mechanism.SOLUTION: A liquid pressure feed device 1 includes: a float 24 housed inside of a container 2 and detecting a liquid level of a liquid W stored in the container 2; opening/closing valves 20 and 22 opening and closing on the basis of a liquid level WL detected by the float 24; and an operation mechanism 26 for connecting the opening/closing valves 20 and 22 and the float 24. The operation mechanism 26 has: an upstream-side link member 32 connected to the float 24; a downstream-side link member 36 connected to the opening/closing valves 20 and 22; a plurality of intermediate link members 34 and 36; and a spring member 30. These members 30, 32, 34, 36 and 38 are rotatably connected. The downstream-side link member 38 has a contact portion 52 which is brought into contact with the upstream-side link member 32 when the float 24 is raised. By the contact of the downstream-side link member 38 and the upstream-side link member 32 at the contact portion 52, buoyant force of the float 24 acts on the downstream-side link member 38.SELECTED DRAWING: Figure 3
