PURPOSE:To reduce size of spring and solenoid by constructing a valve body with a shaft section and conical flange sections formed at opposite ends of the shaft section. CONSTITUTION:A valve body 16 is constructed with a shaft section 15 and conical flange sections 140, 141 formed at opposite ends of the shaft section 15, while oil paths of longitudinal grooves 150, 151 are made at the outside of said flange sections 140, 141. Because of conical flange section 140, the attraction to be produced before the valve body 16 will strow is lowered when compared with a planar plunger, but when setting the top angle of said conical flange section 140 in the vicinity of 174 deg., attraction of approximately 90% is achieved thereby increase of size of solenoid valve can be suppressed around 10%. |
