FLUID CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/209969
Kind Code:
A1
Abstract:
Provided is a fluid circuit that can continuously drive an amplifying device with a simple configuration. The fluid circuit comprises a first selector valve 8 and a second selector valve 130. According to a change in a fluid pressure to be applied, the first selector valve 8 switches between flow channels 70, 80 that communicate a first pressure-receiving chamber 10-3 and a fluid supply device 6 side, and flow channels 70, 82 that communicate a second pressure-receiving chamber 10-4 and the fluid supply device 6 side. The second selector valve 130 switches flow channels 131, 133 that apply fluid pressure to the first selector valve. The second selector valve 130 has a return means 140 and is provided so as to be capable of reciprocal movement between an operating position to which the second selector valve 130 is moved by the stroke of a piston 120 and a return position to which the second selector valve 130 is moved by the return means 140. The piston 120 and the second selector valve 130 can move independently from each other.
