IPC: H01F7/16
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To reduce impact sound when a plunger returns and improve producibility and quality by attaching an O ring to a shaft and fixing a plunger integrally. SOLUTION: An O ring 1 is attached to a shaft 4. After a spring 5 is inserted, the shaft 4 is fixed to a plunger 7 by caulking. The plunger 7 is attracted to a base 3 by energization to a coil 9. In the process, the shaft 4 is also linked to operate and makes the closing 0 ring 1 open. Meanwhile, when energization to the coil 9 is cut off, the shaft 4 and the plunger 7 are pushed back by operation of the spring 5. Since the shaft 4 is stopped by the O ring 1 of a rubber material and the plunger 7 is also stopped in connection with the shaft 4, it does not collide with a sleeve 8 and a return noise is reduced.
