HYDRAULISCHER STOSSDAEMPFER

摘要

A hydraulic shock absorber with automatically adjustable damper force which actuates an electromagnetic rotary adjuster for a control slide that monitors a sole flow cross section. The rotary adjuster is embodied as a permanently excited single-winding rotary adjuster, and because of its permanent magnetic poles in the rotor, even when it is currentless it furnishes a torque that assures safety resetting of the rotary adjuster if the current fails. The hydraulic shock absorber is intended for controlling the undercarriage of a motor vehicle.
