Claims

[Scope of Claim for Utility Model Registration] A solenoid valve that controls the opening and closing of a flow path that opens to the valve seat by moving a movable plunger toward and away from a valve seat provided in a valve box using the electromagnetic attraction force of a solenoid, A damper hole opening facing the valve seat is provided in the plunger, a cylinder is inserted into the damper hole so as to be freely retractable, and a biasing means is provided in the damper hole for biasing the cylinder in a direction to protrude from the damper hole. A plunger is brought into contact with a valve seat via a cylinder, and the cylinder is provided with a hole that communicates between the inside and outside of a damper hole and closes in close contact with the valve seat when the valve seat is seated. valve.
