  • Controllable or regulatable hydraulic shock absorber
    Patent number: 5244063
    Abstract: A controllable or regulatable hydraulic shock absorber has a damping-control valve designed as a force-proportional valve and has a closing force variable directly or indirectly via a proportional magnet. The damping resistance brought about by the damping-control valve is consequently very largely independent of the stroke speed of the shock-absorber piston.
