Control device for an intake valve or exhaust valve of an internal combustion engine

A control device for an intake valve of an internal combustion engine comprising an adjusting element and a control element. According to the invention, the adjusting element comprises a base body (2) and is displaceably arranged between the control element and the valve. The control element rotates during the operation of the control device. 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. To this end, the invention provides that, ("f") in a control device of this type, the mutual assignment between the one KUB area (3) and the at least two KEB areas (6,7) can be modified among one inside the adjusting element base body (2) by means of the switching means.
