にした流量制御弁。 A pump port, a control flow port, and a surplus flow port are formed in the valve body, and a spool is installed inside the valve body, and the pump port and the control flow port are communicated through a control orifice formed in the spool. , and controlling the amount of movement of the spool in accordance with the pressure on the upstream side of the control orifice, and depending on the amount of movement of the spool,
In a flow control valve configured to control the amount of overlap between a pump port and a surplus flow port, a piston is opposed to the spool, a control rod is protruded from the piston, and the control rod has a multi-stage structure with different diameters. The flow control valve has a structure in which the multistage part is configured to be able to move in and out of the control orifice, and the pressure on the control flow port side is applied to the piston.
