Claims

[Claims for Utility Model Registration] A plunger is provided in a hollow pressure vessel having an opening and a bottom, a plunger having a rod attached to one end and a stopper made of a non-magnetic material at the other end. is inserted into the plunger and held so that it can reciprocate so that the stopper moves toward and away from the bottom of the pressure vessel. A valve seat is provided near the opening of the pressure vessel, and the rod moves toward and away from the valve seat as the plunger moves back and forth. What is claimed is: 1. A solenoid valve in which opening and closing of the valve is controlled by: a solenoid valve comprising: a damper provided at an end of the plunger on the bottom side of the pressure vessel;
