Claims

[Scope of utility model registration request]

The lower annular magnetic pole core is joined to the lower end of a cylinder in which a plunger moves up and down, and the upper end of the cylinder is joined to the lower end of the upper magnetic pole core. In a solenoid valve in which a bolt part protrudes through the cover and a nut is screwed into the bolt part to fix an integrated magnetic pole core to the cover, the cylindrical body is slightly narrowed at its upper end and narrowed at its lower end. The upper end of the magnetic pole core on the upper side is tapered in the same shape as the upper end of the cylinder, and the center hole of the annular magnetic pole core on the lower side is in the same shape as the lower end of the cylinder. The lower annular magnetic pole core is fitted and held in the lower end of the cylindrical body, and the upper magnetic pole core is inserted into the upper end of the cylindrical body. A solenoid valve characterized in that the upper magnetic pole core, the cylindrical body, and the lower annular magnetic pole core are integrated and fixed to the cover by screwing a nut portion into a bolt portion protruding from the cover.
