Abstract
A hydraulic camshaft adjuster has a stator, a rotor arranged movably with respect to the stator, and a central valve via which oil supply of working chambers of the hydraulic camshaft adjuster is controlled. A deformable sealing sleeve is arranged between the central valve and the rotor. The sealing sleeve has an initial length in an axial direction, and after assembly, has a deformation such that the length of the sealing sleeve changes from the initial length to an assembled length. The sealing sleeve bears at least partially in the radial direction against the central valve and against the rotor.
