FLUID PRESSURE SYSTEM, PRESSURE ACCUMULATION METHOD OF ACCUMULATOR, AND OPERATIONAL METHOD OF FLUID PRESSURE ACCUMULATOR

摘要

A fluid pressure system (100) is provided with: a first fluid pressure pump (11) for discharging an actuating fluid used for actuating fluid pressure actuators (1-4); a second fluid pressure pump (12) provided in parallel with the first fluid pressure pump (11), the second fluid pressure pump (12) discharging an actuating fluid; an accumulator (30) capable of accumulating the actuating fluid discharged from the second fluid pressure pump (12); and a first switching valve (51) for supplying actuating liquid that has accumulated in the accumulator (30) to the fluid pressure actuator (4) when switched to an open state (51c).
