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.

A valve drive comprising:
- a sliding cam element that is disposed on a carrier shaft so as to be axially displaceable along an axis of rotation of the carrier shaft, wherein the sliding cam includes a first cam profile group with cam profile sections of mutually different form and a second cam profile group with cam profile sections of mutually different form, wherein the cam profile sections of the first cam profile group are the same as the cam profile sections of the second cam profile group;
- and
- a pick-off element by way of which a control movement is picked off from the cam profile sections and transmitted to a valve, wherein the two cam profile groups interact with the pick-off element to jointly control the valve.
A valve drive comprising:
- a sliding cam element disposed on a carrier shaft and axially displaceable along an axis of rotation of the carrier shaft, wherein the sliding cam includes a first cam profile group having different cam profile sections;
- and
- a pick-off element by way of which a control movement is transferred from the cam profile sections to a valve, wherein the first cam profile group interacts with the pick-off element to control the valve.
