Abstract

A camshaft arrangement includes a cam mounted for angular motion on a camshaft with the angular motion being limited by cooperating stops in the camshaft and in a neck portion of the cam defining an interchamber filled with damping fluid. Damping fluid is supplied to the interchamber by a passage in a camshaft bearing sleeve which is in communication with a longitudinal passage in the camshaft through a valve designed to prevent the longitudinal passage from draining.
