Abstract

A cam phaser for a cam shaft arrangement including an inner cam shaft and an outer cam shaft arranged concentrical relative to the inner cam shaft, the cam phaser including at least one rotor; at least one stator; and at least one compensation element configured to compensate axial and/or radial and/or angular tolerances, wherein the stator is connectable torque proof at least indirectly through a drive gear with the outer cam shaft and the rotor is connectable torque proof with the inner cam shaft, wherein the drive gear is separate from the stator and attachable torque proof at the outer cam shaft, wherein the stator is rotatably supportable on the inner cam shaft, wherein plural compensation elements are provided which are arranged evenly distributed in a circumferential direction, wherein the compensation elements are configured torsion stiff in the circumferential direction and attached between the stator and the drive gear.
