Abstract
A switchable cam follower (1) for a valve train (1b) of an internal combustion engine (1c) which is indirectly actuatable via tappet push rods (1a), the cam follower (1) comprising an outer section (2) which encloses an inner section (4) that is axially movable relative thereto, the outer section (2) having a pot-shaped configuration with a bottom (6) which comprises an end (5) for cam contact and separates the inner section (4) from a cam (4a) whereby upon coupling of the sections (2, 4) by a coupling means (23), a high lift of a gas exchange valve (22a) is effected, and upon uncoupling of the sections (2, 4), a zero lift, the cam follower (1) having a relatively simple structure with only a small design space requirement and can be installed in receptions (20a) of the internal combustion engine (1c) as provided hitherto for non-switchable cam followers.
