CONTROLLABLE VIBRATION DAMPERS FOR MOTOR VEHICLES

摘要

Controllable vibration dampers for motor vehicles that include a cylinder which contains a damping medium and an axially movable piston rod sealed and submerged in the medium. A damping piston is attached to the piston rod and subdivides the cylinder into a two work chambers. A hollow piston is provided with at least one valve disc which is movable within the piston. The disc moves into and out of engagement with ledge or edge structures provided within the piston when a dampening medium is directed against and past the disc.
