Abstract
The invention pertains to an automatic decompression device for valve-controlled internal combustion engines, having at least one camshaft for the actuation of gas shuttle valves and a decompression lever, which acts in cooperation with at least one gas shuttle valve and which is attached in a pivoting fashion on the camshaft on an axis of rotation, and which can be moved against a spring force from a first switch position into a second switch position as a result of the centrifugal forces acting on it during the revolution of the camshaft. It is suggested that the decompression lever be designed as a bow element the two ends of which are attached to the camshaft. The decompression arrangement is distinguished by a simple design, and is especially well-suited for small engines due to its lightweight construction.
