Patent ID: 7963261

Claim:
A valve drive for an internal combustion engine having a lever which opens and closes a valve and which can be pivoted with respect to a support point by a cam of a camshaft, with a) the cam being movable into a first axial position and into a second axial position, having a first cam track which acts in the first axial position and a second cam track which acts in the second axial position, and b) the support point is variable to vary the lifting movement of the valve, the support point is formed by a support element which is switchable with a first switching sition in which the support point is fixed with a second econd switchin position in which the support point is movable during a rotation of the camshaft, and c) the second cam track has a smaller lift than the first cam track and a idle stroke of the support element is dimensioned such that, during a rotation about the entire second cam track, the support point is moved by the idle stroke in one direction and then back again, while the valve remains at least unmoved.
