Abstract
A camshaft adjuster () having a vane-type design with a stator () and a rotor (), which can be rotated relative to the stator (), and at least two pressure chambers () formed between the stator () and the rotor (). The pressure chambers () are separated from each other by a radially oriented vane () of the rotor (), wherein the pressure chambers () can be alternately supplied with a pressure medium. The vane () has a radial face () and two lateral faces () that are directed toward the pressure chambers (). The radial face () is sealed by a U-shaped sealing element () having a main limb () and two side limbs () seated against the lateral faces (). The pressure chambers () of the camshaft adjuster () are sealed particularly reliably by designing check valves () on the side limbs () of the sealing element () and by designing, on the lateral faces () of the vane (), outlets for the pressure medium with which the check valves () are associated.
