The invention relates to a rotary actuator system (1, 1a) for controlling the stroke of at least two gas exchange valves (2, 2', 3, 3') with an identical action in a cylinder head (4) of an internal combustion engine. Said system consists of a first pivoting motor (5), equipped with a first shaft (6), on which at least one first actuating element (7, 7a) is located and a second pivoting motor (5 ), equipped with a second shaft (6'), on which at least one second actuating element (7', 7a') is located. One actuating element (7, 7a, 7', 7a') is provided for at least one gas exchange valve (2, 2', 3, 3') and the first and second pivoting motors (5, 5') are point-symmetrical. A force transmission element (8, 8a, 8', 8a') is located between the actuating element (7, 7a, 7', 7a') and the gas exchange valve (2, 2', 3, 3'). The inventive configuration in the valve train reduces the masses that are displaced, permitting higher speeds during the operation of the internal combustion engine. |
