Cam phaser

A cam phaser, comprising:

• a rotation phaser;
• and
• a hydraulic valve hydraulically loading the rotation phaser,
• wherein the hydraulic valve is connectable torque proof with a cam shaft so that the cam shaft is rotatable relative to the rotation phaser,
• wherein the rotation phaser includes a stator and a rotor configured coaxial with the stator,
• wherein the rotor is rotatable relative to the stator,
• wherein the hydraulic valve protrudes at least partially into the rotation phaser,
• wherein an adapter provides relative axial positioning of the rotor and the stator,
• wherein the adapter is loosely mountable in the rotation phaser so that a fixated connection of the adapter in the rotation phaser is provided when the cam shaft is mounted at the hydraulic valve,
• wherein the drive wheel is arranged in a radial direction on an annular shoulder of the adapter, and
• wherein a radial clearance is provided between the annular shoulder and the drive wheel.
