Claims

[Scope of utility model registration request]

A plunger is arranged between the seat member and the core, a spring always urges the plunger toward the seat member, and a coil arranged outside the plunger is energized, so that the plunger resists the urging force of the spring and moves toward the core. In the electromagnetic valve configured to open a valve seat provided in a seat member by attracting the plunger to the side, the plunger may include a magnetic material that also serves as a valve body, and the seat member may include a drain hole. and a solenoid valve comprising a non-magnetic material having a bearing portion of the plunger.
