Claims

[Scope of utility model registration request]

(1) A valve body having at least two flow paths, a fixed iron core, a movable iron core that can move toward and away from the fixed iron core, a spring that applies a biasing force in the return direction to the movable iron core, and a spring provided on the movable iron core. a valve body that opens and closes the flow path of the valve body; an excitation coil that is wound around the fixed and movable iron cores; a frame that faces the movable iron core through a frame, a permanent magnet with one magnetic pole end provided on the frame, and a hollow portion provided on the other magnetic pole end of the permanent magnet and into which the movable iron core is inserted. a magnetic body, a gap gl between the circumferential surface of the hollow part of the magnetic body and the movable core, a gap g2 between the circumferential surface of the cutout part of the frame and the movable core, and a separation between the movable core and the fixed core. A solenoid valve device characterized in that each gap is set in the relationship of g3>g2≧g1, where g3 is the gap in the state. −

(2) The electromagnetic valve device according to claim 1, wherein the movable iron core includes a tapered portion so that the gap g2 between the movable iron core and the frame changes as it moves.
