The first cam comprises a base circle region and a valve lift region with a limiting section which adjoins the base circle region of the first cam. The second cam has a base circle region and a valve lift region with a limiting section which adjoins the base circle region of the second cam. The limiting section of the first cam and the limiting section of the second cam are of identical configuration and are arranged at an identical circumferential position about the longitudinal axis of the camshaft.
