Abstract
A valve train for an internal combustion engine may include a cam shaft and a cam follower. The valve train may also include a first cam arranged on the cam shaft for conjoined rotation. The valve train may further include a second cam arranged on the cam shaft for conjoined rotation and axially adjacent to the first cam. The cam follower may be axially adjustable between a first position, in which the cam follower is drive-connected to the first cam, and a second position, in which the cam follower is drive-connected to the second cam. The cam follower may include a mechanical adjustment device interacting with the cam shaft for axially adjusting the cam follower between the first position and the second position.
