Abstract

Die Vorrichtung zur Betätigung eines Gaswechselventils einer Brennkraftmaschine hat ein auf den Ventilschaft (X) wirkendes Antriebselement (12) und zwei beiderseits des Antriebselements in axialer Richtung voneinander beabstandete Aktuatoren (14, 16). Der Hub des Gaswechselventils ist durch Einstellung des wirksamen axialen Abstandes der Aktuatoren (14, 16) variabel.

Figure 00000001
The device for actuating a gas exchange valve of an internal combustion engine has a drive element (12) acting on the valve stem (X) and two actuators (14, 16) spaced apart from one another in the axial direction on both sides of the drive element. The stroke of the gas exchange valve is variable by setting the effective axial distance between the actuators (14, 16).
