Claims

[Scope of utility model registration request]

A valve arranged to be movable in the axial direction within the solenoid valve body, a plunger attached to the rear end of the valve, and arranged behind the plunger to attract the plunger and move the valve in the axial direction within the solenoid valve body. The electromagnetic valve is characterized in that the valve tip is in line contact with the solenoid valve body and the seal diameter and the movable part diameter are set so as to balance the pressure of the movable part consisting of the valve and the plunger. valve.
