FLUID PRESSURE TRANSMISSION DEVICE

Title:

FLUID PRESSURE TRANSMISSION DEVICE

Document Type and Number:

WIPO Patent Application WO/2011/033934

Kind Code:

A1

Abstract:

Provided is a fluid pressure transmission device which can be downsized and the weight of which can be reduced. The fluid pressure transmission device is provided with a high pressure driving fluid pressure cylinder (75); a plurality of low pressure driving fluid pressure cylinders (71 - 74); a plurality of driven fluid pressure cylinders (51 - 54) which are connected to the low pressure driving fluid pressure cylinders (71 - 74), respectively, via low pressure side fluid pressure transmission paths (61 - 64), respectively; and a high pressure side fluid pressure transmission path (65) which is connected to the high pressure driving fluid pressure cylinder (75). The high pressure side fluid pressure transmission path (65) is connected to the low pressure side fluid pressure transmission paths (61 - 64) via flow path selector valves (91- 94). The flow path selector valves (91- 94) are configured in such a way as to be switchable between a low pressure path state and a high pressure path state, the aforementioned low pressure path state being a state where the low pressure driving fluid pressure cylinders (71 - 74) and the driven fluid pressure cylinders (51 - 54) are connected, and the aforementioned high pressure path state being a state where the high pressure driving fluid pressure cylinder (75) and the driven fluid pressure cylinders (51 - 54) are connected.
