Claims

[Scope of utility model registration request]

A plunger is placed between the valve seat and the core, and a compression spring constantly biases the plunger toward the valve seat.By energizing a coil placed on the outside of the plunger, the plunger resists the force of the compression spring and moves toward the core. In a solenoid valve that opens an orifice hole provided in a valve seat by suction to the side, a step parallel to the end of a plunger built into the cover body is provided on the upper edge of the cover body that is integrally connected to the valve seat. A structure in which the stroke of the plunger is set by a core of a predetermined height according to the distance between the end of the plunger or the top surface of the shim installed on the end face of the plunger and the step, and the collar of the core is tightened with the outer periphery of the cover body. A solenoid valve characterized by:
