た電磁式比例流量制御弁。 A valve housing with an input port and an output port, a solenoid coil, a yoke magnet,
a motor housing equipped with an electromagnetic mechanism consisting of a fixed core and a movable core; a valve that is integrally movable with the movable core and that allows the electromagnetic mechanism to control opening and closing of communication between the input port and the output port; The outer peripheral edge has an effective area equivalent to the sealing area, and the outer peripheral edge is airtightly attached at the junction of the valve housing and the motor housing, and the inner peripheral edge is attached to the movable core so that the inside of the valve housing can be communicated with both the ports. A diaphragm is provided that divides the pressure chamber into a back pressure chamber of the pressure chamber, and the valve and the movable core are provided with a communication hole that communicates the pressure chamber and the back pressure chamber, and the valve is connected to the movable core. An electromagnetic proportional flow control valve is mounted so as to be movable relative to the movable core against the rubber elasticity of the inner peripheral edge of the mounted diaphragm.
