接続してなる流量制御弁。 A first orifice disposed in a passage that guides fluid discharged from the pump to an actuator, a spool that slides against a spring due to a pressure difference between the upstream side and the downstream side of this first orifice, and this spool. The flow control valve is equipped with a drain passage that opens in a portion of the passage between the pump and the orifice when the first orifice slides against a spring, and releases a part of the liquid discharged from the pump to the reservoir. A chamber in which downstream pressure is applied to the end surface of the spool is connected to the passage downstream of the first orifice through a second orifice, and a bench lily portion is provided in the drain passage, and the bench lily portion and the chamber are connected to each other through a second orifice. and a flow control valve connected through a third orifice.
