Claims

[Claim for Utility Model Registration] A plunger is reciprocatably inserted into the inner periphery of a cylindrical solenoid body in which a coil is incorporated, one end of the solenoid body is closed, and a center post is fitted and fixed to the other end. Assemble the valve box to the center post side end of the solenoid body, insert the rod tip integrally fixed to the plunger into the valve box through the guide hole provided in the center post, and then separate the plunger from the center post. In a solenoid valve that is provided with a biasing means for biasing in a direction and opens and closes a flow path by moving a rod in a valve box forward and backward, the solenoid valve penetrates through the rod and a plunger, and the plunger inside the valve chamber and the solenoid main body. A through passage communicating with the plunger chamber on the end surface side is provided, and a groove is separately provided in the plunger and the center post to communicate the plunger chamber and the valve chamber, and the through passage and groove connect the valve chamber and the plunger chamber. A solenoid valve comprising a circulation path connecting the two.
