Abstract:

A switchable cam follower (1) for a valve train of an internal combustion engine, which valve train is actuated by tappet push rods, the cam follower (1) comprises an outer section (4) and an inner section (5) which are adapted to be switched off through a coupling device (22) by the lift of a loading cam, a locking device (27) associated with the coupling device (2) and cooperates with a single track on the cam, the locking device (27) prevents displacement of the coupling device (2) outside of a defined part of the base circle phase of the cam.
