A camshaft adjuster for an internal combustion engine of a motor vehicle, having a stator and a rotor accommodated inside the stator such that the rotor can rotate relative to said stator, wherein the rotor has at least one rotor vane, which extends in the radial direction towards an inner wall of the stator and forms a first hydraulic chamber and a second hydraulic chamber between the stator and the rotor, wherein a connection gap remains between a rotor vane end face and the inner wall of the stator and fluid-connecting the first hydraulic chamber and the second hydraulic chamber. A sealing element is guided in a radially movable manner in the rotor vane end face to and fro between a sealing position, in which the sealing element bears against the inner wall of the stator to seal off the connection gap, and a connecting position, in which the first and second hydraulic chambers are connected to each other through the connecting gap. |
