Abstract
A valve drive may include a sliding cam element that is held on a carrier shaft so as to be axially displaceable along an axis of rotation of the carrier shaft. The sliding cam element may include at least one cam profile group with cam profile sections of mutually different form. The valve drive may further include a pick-off element by way of which a control movement can be picked off from the cam profile sections and transmitted to a valve. The sliding cam element may also include a second cam profile group that is similar or identical to the first cam profile group and, which for the joint control of one valve, may interact with the pick-off element.
