Camshaft adjuster for internal combustion engines of motor vehicles

A camshaft adjuster for a camshaft of an internal combustion engine of a motor vehicle, the camshaft adjuster comprising:

• a stator;
• a rotor rotatable relative to the stator;
• wherein between the stator and the rotor pressure chambers are defined;
• at least one valve;
• lines connecting the at least one valve to the pressure chambers;
• wherein the at least one valve is configured to supply a pressure medium to the pressure chambers, respectively;
• wherein the at least one valve is arranged on a side of the camshaft adjuster facing away from a connection of the camshaft adjuster to the camshaft,
• wherein the at least one valve has a valve housing provided with a radially outwardly oriented flange;
• a lid covering the at least one valve, wherein the lid is fastened to the flange of the valve housing.
