Damping device for movable masses, preferably for electromagnetic systems

A damping device for an electromagnetic valve control of an internal combustion engine, said damping device comprising:

• a pressure chamber (15, 54, 55, 79, 82);
• a hydraulic supply line (25, 60, 62, 80, 81) communicating with said pressure chamber (15, 54, 55, 79, 82) and supplying said pressure chamber (15, 54, 55, 79, 82) with a hydraulic medium;
• a first damping piston (13) positioned at one side of said pressure chamber (15, 54, 55, 79, 82) and movable relative to said pressure chamber (15, 54, 55, 79, 82);
• a moveable mass (5, 6, 47, 75, 37, 42) acting on said first damping piston (13);
• wherein, when said first damping piston (13) is moved in a first direction by said moveable mass (5, 6, 47, 75, 37, 42) from a rest position into said pressure chamber (15, 54, 55, 79, 82), the hydraulic medium is initially displaced from said pressure chamber (15, 54, 55, 79, 82) into said hydraulic supply line (25, 60, 62, 80, 81) until said hydraulic supply line (25, 60, 62, 80, 81) is closed off by said first damping piston (13) and a hydraulic pressure is generated in first pressure chamber (15, 54, 55, 79, 82) to create a force acting counter to a movement of said moveable mass (5, 6, 47, 75, 37, 42).
