Abstract

A hollow-cylindrical camshaft may include a closing cover and supply openings. Slipping of the closing cover may be prevented by indentations introduced into the camshaft. The indentations may be inwardly rolled portions, impressions, notches, or plastic deformations, for instance, introduced from the outside by punches or holding means that project into the interior of the camshaft. The indentations may be arranged in one or more planes orthogonal to an axial direction of the camshaft, wherein the indentations are rotationally symmetrical or can be arranged symmetrically or asymmetrically. The indentations can be mounted in the axial direction either between the closing cover and the supply opening located closest to the closing cover, or at the same axial positioning as the supply opening such that slipping of the closing cover over the supply opening is prevented.”
