Title:
FLUID CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/209968
Kind Code:
A1
Abstract:
Provided is a fluid circuit capable of continuously driving an amplifier with a simple configuration. The present invention comprises: a first switching valve 8 for switching between flow paths 70, 80 and first flow paths 80, 81 in accordance with a change in fluid pressure to be applied; a second switching valve 130 for switching a flow path that applies a fluid pressure to the first switching valve 8 when a piston 120 reaches a starting end position or reaches a terminating end position; and second flow paths 123, 125. A biasing force FS2 of a biasing means 140 exerted when the piston 120 reaches the terminating end position is smaller than a pressing force FH1 exerted on the piston 120 due to a fluid pressure by a fluid supply device 6, and a biasing force FS1 of the biasing means 140 exerted when the piston 120 reaches the starting end position is larger than a sum of a flow path resistance R1 exerted on the first flow paths 80, 81 and a flow path resistance R2 exerted on the second flow paths 123, 125.
