制御弁。 A solenoid that generates a force proportional to the current, a spool whose output pressure is guided to one end as feedback pressure, and whose position is determined by the balance between this feedback pressure and the force of the solenoid, and a spool that is positioned according to the sliding position of this spool. In a proportional control type pressure control valve comprising a supply port and a drain port whose communication with an output port is controlled by a pressure control valve, a correction pressure chamber is defined so as to oppose the feedback pressure, and a correction pressure chamber is provided in the correction pressure chamber. , a pressure control valve characterized in that the output pressure is guided through a first-order delay element consisting of an orifice and an accumulator.
