Abstract

A camshaft adjuster which operates according to the vane-type motor principle, which means being able to move to and fro within a certain angle, generally comprises a stator and a rotor. The rotor itself is provided as a composite system of at least two components. One of the components is a cover. A further component of the composite system may be denoted as the rotor core. The cover is placed on the rotor.
