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.
