Control device for switching intake and exhaust valves of internal combustion engines

摘要

A control device for switching an intake or exhaust valve of an internal combustion engine has a control valve with a control valve piston for controlling flow of a hydraulic medium from a pressure line to the intake or exhaust valve. At least one actuating element is correlated with the intake or exhaust valve and has a first end acted on by the hydraulic medium. At least one damping device interacts with the at least one actuating element and is arranged at a second end of the actuating element opposite the first end. The at least one damping device exerts a damping force onto the actuating element counteracting a force exerted by the hydraulic medium.
