The cam roller has a bore and the bore is mounted by on a pin which is seated at the ends in receptacles of opposite walls of the pocket. The cam roller runs with its end sides directly in front of the walls. Each end side of the cam roller takes the form of an outer surface of a spherical zone, and each wall is smooth and straight, at least in the region of its run-on piece at the respective end side of the cam roller.

Abstract: In a guide rail for the valve train of an internal combustion engine, having receiving spaces disposed in an elongate body in spaced-apart relationship behind one another and accommodating valve lifters, flats are formed upon the outer surface area of each valve lifter to prevent the lifter from rotating about its central longitudinal axis. These flats are supported by flats of the guide rail which are located within the pertaining receiving space. An inlet bore is assigned to each receiving space of the elongate body for insertion of the valve lifter with an attached trumpet-like end in direction of its longitudinal axis. Subsequently the valve lifter is shifted in axis-parallel relationship to the flats of the guide rail, which act as rotation-inhibiting surfaces, and then is slightly displaced again in axial direction.
