Claims

[Claims for Utility Model Registration] (1) A yoke 1 provided with an excitation winding 2, a movable plunger 3 that cooperates with the yoke 1 to form a magnetic path, and a movable plunger 3 from the yoke 1. The opening/closing electromagnetic valve is constituted by a spring 6 that biases in the direction of separation, and a valve body 7 that operates integrally with the movable plunger 3 to conduct and cut off the fluid passage. yoke 1
When drawing the movable plunger 3 that has been separated from the yoke 1 to the yoke 1, a current sufficient to draw the movable plunger 3 to the yoke 1 is applied to the excitation winding 2, and the movable plunger 3 After being attracted to the yoke 1, the excitation winding 2 and the movable plunger 3 are connected to the yoke in an opening/closing solenoid valve which is provided with means for preventing leakage of magnetic flux in order to reduce the current that maintains the attraction as much as possible. A first excitation winding 2a for attracting and adhering to 1 and a second excitation winding 2b for maintaining the adsorption.
an annular groove 10 is formed in the suction plane 8 of the yoke 1 with the movable plunger 3;
An on-off solenoid valve characterized in that the second excitation winding 2b is disposed in the annular groove 10. (2) The yoke 1 is formed in a pincushion shape with flanges 1a and 1b at both ends, and the two flanges 1a,
The first excitation winding 2a is arranged between 1b,
The movable plunger 3 is formed into a bottomed cylindrical shape housing the yoke 1, and the bottom inner surface of the bottomed cylindrical movable plunger 3 and one flange portion 1a of the yoke 1 are connected to each other.
suction planes 9 facing each other with the outer end surfaces of the
8, and the second excitation winding 2b is inserted into the annular groove 10 formed in the attraction plane 8 of the yoke 1.
The opening/closing solenoid valve according to claim 1, wherein the utility model registration solenoid valve is arranged.
