Rotating control element circumferential areas with contours that vary in the circumferential direction are provided as control cams throughout the rotating control element. Force introduction areas KEB (6, 7), which are positioned in a non-uniform manner, and a force transfer area KUB (3) are provided on the base body (2) of the adjusting element. Switching means for the alternately M contacting assignment of the KEB areas (6, 7) are provided on the different control cam areas of the control element The aim of the invention is to enable the largest possible number of different controls for an engine valve.
