Title:
減衰力調整式緩衝器およびソレノイド
Document Type and Number:
Japanese Patent JP7217756
Kind Code:
B2
Abstract:
Between a first stator core and a second stator core configuring the main part of the solenoid, a nonmagnetic ring is provided positioned on the inner periphery side of a coil. The nonmagnetic ring is bonded by brazing between a first and second fixed iron core (the first and second stator cores) so as to increase the magnetic circuit magnetic flux density in a movable iron core (a plunger). The inner diameter of the nonmagnetic ring, which is formed from a nonmagnetic material such as austenitic stainless steel, is larger or smaller than the inner diameter of the first and second stator core, and an axial gap is formed between the nonmagnetic ring and the plunger.
