Abstract
The present disclosure concerns a slotted guide of a valve train of an internal combustion engine. The slotted guide includes two guide tracks, which cross one another in a crossing region, for guiding a switching pin of a cam follower of the valve train. The two guide tracks have an on-track region, a crossing region, and an off-track region. At least one radial projection, structured and arranged to protrude beyond the slotted guide in a radial direction, is provided in or downstream from the off-track region of at least one guide track.
