Patent ID: 8434438

Claim:
A camshaft adjuster for an internal combustion engine of a motor vehicle, comprising: a radially outer stator which can be driven by a crankshaft of an internal combustion engine; a radially inner rotor which is connected to a camshaft in a rotationally fixed manner; working chambers which are arranged between the rotor and the stator and can be pressurized in such a manner that a relative rotational position of the rotor with respect to the stator can be changed; at least one sealing cover which laterally delimits the working chambers and bears against the stator and/or the rotor, the at least one sealing cover having a bore receiving a fastener therethrough for fastening the at least one sealing cover to the stator and/or the rotor, wherein at least one of the sealing cover, the stator, and the rotor has a convex, concave or conical bearing surface such that a gap is present between the at least one sealing cover and the stator and/or the rotor at least in the area of the bore prior to tightening the fastener, and the sealing cover can be elastically deformed to close the gap by tightening the fastener, and a sealing force is exerted between the at least one and the stator and/or the rotor by elastic deformation of the sealing cover when the fastener is tightened.
