Abstract
A valve drive comprising a camshaft with base shaft, a lobe pack mounted on the base shaft and comprising three cam lobes. Two actuator bodies are associated with two actuator pins each connected to a valve of a cylinder of the engine. The lobe pack is axially displaceable along the base shaft so as to for each actuator body change cam lobe aligned therewith. A middle cam lobe has a shape leaving an actuator body aligned therewith uninfluenced thereby. In a first position of the lobe pack a first of the actuator bodies is aligned with and hit and moved by a first cam lobe and the other, second actuator body is aligned with the middle cam lobe, and in a second position the second actuator body is aligned with and hit and moved by a third cam lobe and the first actuator body is aligned with the middle cam lobe.
