弁。 An orifice disposed in a passage that guides the discharge fluid of the pump to the actuator, a spool that slides against a spring due to the differential pressure between the upstream and downstream sides of this orifice, and a spool that slides against a spring. One end surface of the spool exposed to the passage in a flow rate regulating valve equipped with a drain passage that opens at a portion of the passage between the pump and the orifice by sliding displacement to release excess liquid discharged from the pump to a reservoir. A flow rate adjustment valve with a concave shape.
