Damping device for moving masses, preferably for electromagnetic drive systems

摘要

The damping means is in particular for cam shafts loosely electromagnetic valve control units provided in internal combustion engines. It has a damping element, the one of the mass to be moved opposite force. Dollars a by the damping device in such a way that it operates quietly, a long service life and reliably on the shortest possible path to a standstill, brakes, the damping element is a damping piston, which defines a pressure chamber. In this opens a hydraulic line which, during the displacement of the damping piston by means of the moving mass, with displacement of the hydraulic fluid from the pressure chamber and under construction of a hydraulic pressure in the pressure chamber is closable. With the damping device, a high noise damping, as well as a long service life of the damping device or of the drive system is achieved. Dollars a the damping device is advantageously suitable for electromagnetic drive systems, which is preferably constructed for cam shafts loosely electromagnetic valve control units are used in internal combustion engines.
