Title:
FLUID CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/209967
Kind Code:
A1
Abstract:
Provided is a fluid circuit capable of stabilizing the flow of a working fluid which flows in an actuator. This fluid circuit comprises a fluid supply device 2 that transmits a working fluid and an accumulator 6 that accumulates the pressure of the pressure-boosted working fluid. A variable throttle valve 9 and the accumulator 6 are provided to a branch flow channel 60 branching from a main flow channel 20 that extends from the fluid supply device 2 to the actuator 5. A first pressure detector 7 is provided between the variable throttle valve 9 and the accumulator 6. In the branch flow channel 60, a second pressure detector 10 is provided between the main flow channel 20 and the variable throttle valve 9. The variable throttle valve 9 can be controlled on the basis of pressures PA, PB detected by the respective detection units 7, 10. The branch flow channel 60 is provided with a check valve 8.
