ABSTRACT:
The specification describes a camshaft arrangement which opens a load-change valve of an internal combustion engine includes a camshaft having a projection which extends beyond what is otherwise a circular cross-section. The camshaft projection limits the relative angular motion between the camshaft and the cam element and includes a buffer which may comprise elastic material or a piston which interacts with a hydraulic medium. The buffer acts to cushion the approach motion of the camshaft projection and the inner wall, or stop, of the cam element, to prevent undesirable noise produced by, or wear of, the camshaft arrangement.
