１、または２記載の電磁弁。[Claims for Utility Model Registration] 1. In the shaft hole formed on the shaft core of the excitation coil,
A fixed core and a movable core are arranged facing each other along the axial direction, and the movable core is attracted to the fixed core when energized, and the movable core attracted to the fixed core is subjected to the biasing force of the return spring when not energized. Therefore, the solenoid valve is equipped with a DC solenoid operating section that is operated by being separated from a fixed iron core, and is characterized in that one of opposing surfaces of the fixed iron core and the movable iron core is coated with a magnetic elastic material. Solenoid valve. 2 Into the shaft hole formed on the shaft core of the excitation coil,
A fixed core and a movable core are arranged facing each other along the axial direction, and the movable core is attracted to the fixed core when energized, and the movable core attracted to the fixed core is subjected to the biasing force of the return spring when not energized. Therefore, the electromagnetic valve is equipped with a DC solenoid operating section that is operated apart from a fixed core, and a recess is formed in one of the facing surfaces of the fixed core and the movable core, and when energized, the A magnetic elastic body that is loosely inserted into the recess and whose tip end surface is attracted to the bottom surface of the recess is protruded from the other side, and the protruding width of the magnetic elastic body is slightly larger than the depth of the recess. solenoid valve. 3. The electromagnetic valve according to claim 1 or 2, wherein the magnetic elastic body is formed by mixing soft magnetic powder into an elastic base material.
