Abstract:
1. A camshaft adjustor for internal combustion engines of motor vehicles, the camshaft adjustor comprising: a stator having a casing and stays connected to the casing and projecting radially inwardly; a rotor rotatable relative to the stator and configured to be fastened on a camshaft of an internal combustion engine; wherein the rotor has a rotor base member and vanes connected to the rotor base member; wherein the vanes project into spaces between the stays of the stator, respectively; wherein the stays each have an end face that rest sealingly against the rotor base member of the rotor; wherein the vanes of the rotor each have an end face resting sealingly against an inner peripheral wall of the stator; wherein at least one of the vanes of the rotor has at least one damping element and wherein the stator has at least one counter damping element, wherein upon rotation of the rotor into an end position of the rotor the at least one damping element interacts with the at least one counter damping element; wherein the at least one damping element is a groove provided in a vane sidewall of the at least one rotor vane; wherein the at least one damping element is provided at a spacing from the end face of the at least one rotor vane; wherein the at least one damping element is provided at approximately half a radial length of the vane sidewall of the rotor vane.
