Solenoid valve

Abstract

Abstract PURPOSE:To prevent the locking of a plunger due to the bite of foreign matter by making up the plunger of a movable member consisting of a magnetic material, and a shaft, and by forming, in a spool, a recess in which one end of the shaft is to be fitted. CONSTITUTION:A plunger 15 is made up of a movable member 15a consisting of a magnetic material, and a shaft 15b consisting of a nonmagnetic material and having been coaxially connected to the movable member 15a, and in one end of a spool 32, a recess 52 whose diameter is a little smaller than that of the shaft 15b is formed. In this recess 52, one end of the shaft 15b is pressedly fitted. Thereby, the plunger 15 can be floated from the fitting hole 14, thus the locking of the plunger 15 due to the bite of foreign matter can be prevented.
