Abstract

A valve drive for an internal combustion engine may include a cam shaft, at least one cam follower, and at least one adjusting device. The at least one adjusting device may include a first adjustable engagement element and a second adjustable engagement element. The first engagement element may not contact a first guide in an initial position, and may cooperate with the first guide in a switching position. The second engagement element may not contact a second guide of a slide guide in an initial position, and may cooperate with the second guide in a switching position. The at least one adjusting device may further include a switching arrangement that may include a first control element mounted to the first engagement element and a second control element mounted to the second engagement element. The first control element and the second control element may be controllable via the switching arrangement.
