Title:
SOLENOID VALVE
Document Type and Number:
Japanese Patent JP2009275811
Kind Code:
A
Abstract:

To provide a solenoid valve capable of reducing abrasion of iron cores by absorbing impact of the movable iron core with respect to the fixed iron core while preventing leaking of fluid by a simple configuration.

A solenoid part 41 of the solenoid valve 11 has a fixed magnetic pole member 45. The fixed magnetic pole member 45 is comprised by supporting an exciting coil 43 wound on a shaft part 46 via an insulating tape 39 between first and second bobbins 48a, 48b. The solenoid part 41 has the movable iron core 33 housed in an iron core chamber 32 provided recessed from a mounting face 22a in a body 22. An impact buffering material 50 is interposed between a mounted face 45a of the fixed magnetic pole member 45 to the body 22, and the mounting face 22a of the body 22, and the solenoid part 41 is partitioned into the movable iron core 33 and the fixed iron core 45 by the impact buffering material 50. A gasket 51 carrying out sealing between the mounting face 22a and the impact buffering material 50 is provided in a periphery of the iron core chamber 32 in the mounting face 22a.
