Abstract

An actuating device for a decompression valve of an internal combustion engine with a cable starter, wherein the decompression valve is positioned within the cylinder of the internal combustion engine and comprises a valve member biased into its closed position, has a transmission lever having a longitudinal extension and being rotatable about its longitudinal axis. The transmission lever has a first and a second end. A cable drum for receiving the starter cable of the cable starter is provided. The cable drum has an axis of rotation about which the cable drum is rotated when the starter cable is pulled. The longitudinal axis of the transmission lever is perpendicular to the axis of rotation of the cable drum and spaced from the rotational plane of the cable drum. The cable drum entrains the first end of the transmission lever in the direction of rotation and thereby rotates the transmission lever about its longitudinal axis such that the second end of the transmission lever performs an adjusting movement for moving the decompression valve from the closed position into the open position.
