ABSTRACT:
A rotary actuator device is used to control the stroke of at least two gas exchange valves in a cylinder head of an internal combustion engine. The device includes first and second actuating mechanisms, first and second rocker motors, and a force transfer element. Each actuating mechanism is provided for at least one of the gas exchange valves of the engine. The first rocker motor has a first shaft on which the first actuating mechanism is disposed, and the second rocker motor has a second shaft on which the second actuating mechanism is disposed. The first and the second rocker motors are arranged in a point-mirrored relationship. The force transfer element is disposed between each actuating mechanism and the at least one gas exchange valve.
