る油圧制御弁。 A hydraulic control valve that adjusts the opening area of an orifice that communicates between an inlet to which a constant pressure of hydraulic pressure is supplied and a predetermined actuator by electrically controlling a solenoid, and determines the drain flow rate accordingly. A drain port communicating with the actuator is configured separately from the orifice, and the spool that determines the opening area of the orifice and the spool that determines the opening area of the drain port are coaxial with each other and are arranged so that the solenoid is actuated. The orifices are arranged so that they move in the same direction by the spools, and the opening/closing relationship between the orifices and the drain port changes inversely with the movement of each of the spools. Hydraulic control valve.
