SOLENOID VALVE

摘要

PROBLEM TO BE SOLVED: To provide a solenoid valve capable of appropriately driving a movable core in a case of having a fixed core formed with a non-magnetic part. SOLUTION: A movable core 4 is axially movably provided in a hollow part 1c of the fixed core 1 between a valve seat member 3 and a spring 2, and the non-magnetic part 1x is formed in the spring side of the fixed core 1. The movable core 4 has a stepped columnar part having a small diameter part 4b in the spring side and a large diameter part 4c in the valve seat member side, and a stepped part 4d in these boundary. The stepped part and the end of the small diameter part in the spring side are so arranged as to about on the side face of the hollow part 1c of the fixed core.
