比例弁。 20 compound solenoid consisting of a retractable solenoid 19 and a push-out proportional solenoid, each having plungers 23 and 25 at one end of a valve body 1 that incorporates a valve body 16 that is biased in the direction of closing the fluid passage 2 by a spring 18. A rod 26 for operating the valve body 16 is disposed between the valve body 16 and the plunger 25 of the push-out type proportional solenoid 20, and a rod 26 for operating the valve body 16 is disposed between the plunger 25 of the push-out type proportional solenoid 20 and a rod 26 for operating the valve body 16. The valve seat 9 is connected, and the suction characteristic of the extrusion type proportional solenoid 20 and the spring constant of the spring 18 are set to be approximately equal, and the coil 24 of the retraction type solenoid 19 and the coil 27 of the extrusion type proportional solenoid 20 are connected. Connected in series to constant current control circuit 28, both coils 24, 2
A proportional valve with a closing function, characterized in that switching elements Ry1a and Ry2a are connected in parallel to 7.
