Title:
SHOCK ABSORBER AND SOLENOID
Document Type and Number:
WIPO Patent Application WO/2019/130682
Kind Code:
A1
Abstract:
According to the present invention, a part where a clearance between a movable element and a core is small is formed, and a part where the clearance between the movable element and the core is large is formed, and a clearance between a small diameter portion of the movable element and a magnetic portion of the core is optimized in such a way that a lateral force generated in the movable element is reduced while a solenoid thrust is maintained, and it is thus possible to suppress to a minimum a reduction in the solenoid thrust and biasing of the lateral force generated in the movable element, and to improve damping force controllability of a damping force generating mechanism.
