Claims

[Claims for Utility Model Registration] A plunger is inserted into one end of a cylindrical solenoid body so as to be able to reciprocate in the axial direction, and a center post made of a magnetic material is fixed to the other end of the solenoid body to excite the solenoid body.・The plunger is reciprocated by de-energization to open and close the flow path inside the hollow valve body that is assembled to the solenoid body.The center post has a space between the center post and the plunger and the outside. In a solenoid valve provided with a communicating passage, the passage is closed when the pressure of the fluid flowing into the passage between the plunger and the center post is below a predetermined pressure, and when the pressure exceeds the predetermined pressure, the passage is opened to allow the fluid to flow outside. A solenoid valve characterized by being provided with a relief valve for releasing water.
