ABSTRACT:
A guide rail (1, 22) for valve tappets (2) of an internal combustion engine is provided. The guide rail (1, 22) has receptacle spaces (4), which are each used for receiving one of the valve tappets (2) and in which there are flattened sections (6) interacting in a positive-fit connection with key surfaces (7) of the valve tappets (2), such that each of the valve tappets (2) is protected from rotating about its longitudinal axis, with the flattened sections (6) permitting alignment of the valve tappet (2) parallel to the flattened sections (6). Here, the guide rail (1, 22) is formed as a metal carrier (3, 25) and rotational protection elements (8, 9, 23), which are fixed on this carrier, have the flattened sections (6) which also permit alignment of the valve tappet (2) orthogonal to the flattened sections (6), in that each flattened section (6) belonging to one of the receptacle spaces (4) can be displaced relative to the metal carrier (3, 25).
