ABSTRACT:
A vibration damping system for vehicles, with a damping element in a cylinder. The cylinder holds a damping medium and is divided into two chambers by a piston. A damping valve, located in a bypass, is connected parallel to the work cylinder. The damping valve variably controls damping to any desired damping in the decompression and compression stages of operation of the vibration damping system. The damping valve has an axially-movable, controllable valve being disposable in an opening. The controllable valve is connected in a series fluid flow relationship with at least one pressure-controlled, spring-loaded valve within the same valve body. The damping valve can be installed in numerous variations in vibration damping systems of vehicles.
