Claims

[Claims for Utility Model Registration] A cylindrical coil portion having a central hole; a first yoke and a second yoke made of a magnetic material disposed at intervals at both ends of the central hole of the coil portion; , a plunger made of a magnetic material disposed within the first yoke and having a fluid passage in the axial direction; and a cover made of a magnetic material that covers the outer periphery of the coil portion and has a plug hole that communicates the center hole with the outside. a plug adjuster held in the plug hole and in contact with the plunger to restrict movement of the plunger; and a fluid control valve operated by the plunger slidably held on an axial extension of the plunger. and a valve housing coupled to one end of the coil portion, the solenoid valve having a groove or a through hole extending axially from one end to the other end between the plug adjuster and the plug hole. A solenoid valve characterized by having a passage communicating between a central hole and the outside.
