ABSTRACT:
A camshaft arrangement has a series of cams mounted on a camshaft for limited angular motion relative to the camshaft in response to force applied by a closing spring for the associated valve and a series of fixed cams separated by spacer sleeves. All of the cams and spacer sleeves are assembled on the shaft by sliding them on from one end and are retained between stops on the shaft so that they seal recesses in the movable cams which are filled with a damping fluid.
