Abstract

PURPOSE: To safely perform feed of fluid by providing an attractive iron core above a movable iron core, and by providing on the solenoid cover a permanent magnet to attract and retain the attractive iron core at the upward moving position.
CONSTITUTION: An attractive iron core 8 is provided clear of a constant stroke S1 above a movable iron core 9, and a permanent magnet 15 to attract and retain the attractive iron core 8 at the upward moving position is also provided in a cover 14 of a solenoid part 4. Thus, after fluid is once fed through communication with the solenoid part 4, and then shut out due to fault of no electric the electric system or the like, the movable iron core 9 moves down by impetus force of a spring 11 and closes a valve seat 5, but the attractive iron core 8 holds the status as attracted by the permanent magnet 15. In consequence, fluid can be safely supplied offerward, even if the solenoid part 4 is electrically communicated, because the movable iron core 9 holds the status of closing the valve seat 5.
