Abstract

Elektrisch steuerbarer Ventiltrieb für Verbrennungsmotoren, mit einem elektrisch ansteuerbaren Aktuatorelement zum Verschieben eines Ventils, wobei im unbetätigten Zustand das Ventil in Bezug auf das Aktuatorelement ein Ventilspiel aufweist. Zwischen dem Ventilschaft und dem Aktuatorelement ist ein mit einem Fluid gefülltes Dämpfungselement angeordnet, das zwei Fluidvolumina aufweist, wobei beim Betätigen des Ventils Fluid von dem einen Fluidvolumen in das andere Fluidvolumen gedrückt wird.

Figure imgaf001
Electrically controllable valve drive for internal combustion engines, with an electrically actuatable actuator element for displacing a valve, wherein in the unactuated state, the valve with respect to the actuator element has a valve clearance. Disposed between the valve stem and the actuator element is a damping element filled with a fluid having two fluid volumes, fluid being forced from one fluid volume into the other fluid volume upon actuation of the valve.
