Abstract

A camshaft adjuster for an internal combustion engine of a motor vehicle, including a stator which can be driven by a crankshaft of an internal combustion engine and is located radially on the outside, a rotor which is non-rotatably connected to a camshaft and located radially on the inside, working chambers which are disposed between the rotor and stator and can be subjected to a pressure such that the rotational position of the rotor relative to the stator can be varied, and at least one sealing cover which laterally delimits the working chambers and rests against the stator and/or rotor. The sealing cover, stator and/or rotor have a convex, concave or conical contact surface, and the sealing cover can be elastically deformed by the attachment via the contact surface such that it rests against the stator and/or rotor with an increased sealing force as a result of elastic deformation.
