Abstract: A valve drive device has a camshaft which includes a shaft element and a cam piece which can be driven by the shaft element and a first cam effecting a first stroke of a valve and a second cam effecting a second stroke of the valve, and is displaceable in the axial direction of the camshaft relative to the shaft element between a first position, in which the valve can be actuated by the first cam, and a second position in which the valve can be actuated by the second cam, and has an electrically controllable actuator via which the cam piece is displaceable relative to the shaft element in the axial direction as a result of an electrical control of the actuator. The actuator pushes the cam piece alternately back and forth between the positions in the case of successive electrical controls occurring with the same polarity.

Abstract: In a cam element for a valve drive train device of an internal combustion engine having at least one cam comprising at least two partial cams which are arranged next to one another and have a shared base circle phase in at least one angular camshaft range for valve lift switching by displacing their axial position with respect to a cam follower from one of the partial cams to another of the partial cams, the partial cams are angularly displaced in an axially overlapping arrangement. Also, between adjacent partial cams, a circular undercut is formed which has a center that is slightly offset from the rotational axis of the cam element so as to facilitate a switch over of valve actuation from one to another of the adjacent partial cams.
