電磁弁。[Claims for Utility Model Registration] (1) It has a spool connected to a movable core that is attracted to a fixed core that is excited by energizing a solenoid coil, and has an input port, an output port, and a discharge port. In the proportional solenoid valve, the proportional solenoid valve has a spool casing that cooperates with the spool, and movable core support means that movably supports the movable core in the axial direction with substantially no sliding resistance. A forced fluid moving means for forcibly moving fluid in a case containing a solenoid coil, a fixed iron core, and a movable iron core through an appropriate gap is provided so as to move together with the axial movement of the movable iron core. proportional solenoid valve. (2) The forced fluid moving means is a plate member having an outer periphery similar to the contour of the inner periphery of the case so as to form the gap with the inner wall of the case, and the forced fluid moving means 2. The proportional solenoid valve according to claim 1, wherein the moving means deforms the plate member according to the temperature so as to widen the gap when the temperature decreases.
