摘要

The cam shaft (11) has a dog (23) mounted in a shaft (44), which is held in a recess of the dog. The recess is limited by a circular arc-shaped saddle surface that contacts the shaft, where the saddle surface extends over a circumference of the shaft. The dog exhibits a core area (42) and two arms that limit the recess. An edge surface (26) of the dog is turned away from the shaft and exhibits a radius that is continuously reduced from maximum in the core area to a free end of the arms. An independent claim is also included for a cylinder comprising a combustion chamber.
