Title: Solenoid valve
Inventor: WATANABE KAZUCHIKA
IPC: F16K1/32
Filed: 2000-01-17
Abstract: PROBLEM TO BE SOLVED: To provide a solenoid valve for preventing valve leakage by restraining a shaft directional inclination of a movable part with the simple constitution. SOLUTION: A movement of a moving core 16 to the anti-stator core side is regulated by a regulating part 13b of a plate stopper 13, and since the shaft directional inclination of a shaft 14 is regulated by a bearing part 13c of the plate stopper 13, the shaft directional inclination of the shaft 14 is regulated with the simple constitution without increasing the number of part items to thereby improve abutting accuracy of a valve member 17 to a seat part 8c to prevent the valve leakage. Since a projecting part 14a inscribable in an inner wall of a groove part 5a of a stator core 5 is arranged in a stator core 5 side end part of the shaft 14, the shaft directional inclination of the shaft 14 is restrained further.  A shape of the projecting part 14a is formed in a spherical shape or a barrel shape to prevent the projecting part 14a from being fixed to the inner wall of the groove part 5a by the shaft directional inclination of the shaft 14 to further prevent the valve leakage.
