Claims

[Claims for Utility Model Registration] A hollow cylindrical solenoid body incorporating a coil, a center post fixed to one end of a hollow hole in the solenoid body, and a valve disposed opposite the center post. A plunger is inserted between the center post and the valve seat via a bearing section so as to be able to reciprocate, and a spring is installed in the space between the plunger and the center post to press the plunger against the valve seat. In a solenoid valve that presses a plunger against a valve seat using a spring force to keep the valve closed, and when the valve opens, the solenoid body is turned on and the plunger is magnetically attracted to a center post, wherein: between the plunger and the bearing part. 1. A solenoid valve comprising a pressure introducing means for forming a damper gap and introducing fluid pressure into the space between the plunger and the center post.
