Claims

[Scope of Claim for Utility Model Registration] 1. An armature with a flat valve body provided at one end of the armature and a return spring installed at the other end, an operating coil for vertically moving the armature, and a valve body inside the valve housing. It is equipped with a valve seat formed at the upper end that communicates with the water supply port of the drain outlet, and when the coil is energized, the armature is lowered so that the valve body blocks the valve seat, and when the armature is not energized, the spring pressure of the spring is used. A solenoid valve characterized in that the valve body is released from the valve seat by returning to the upper position, and the water supply port and the drain port are brought into communication. 2. The electromagnetic valve according to claim 1, wherein the upper end of the drain port formed in the valve housing has a tapered diameter, and a nozzle portion communicating with the drain port is formed to form a valve seat.
