Claim:
1. A rotary feedthrough for a compressed air supply system is positioned between a stator and a rotor rotating relative the stator, a compressed air channel disposed in the stator is connected to a compressed air line and leads compressed air into an annular chamber formed in the rotor, wherein at least one working channel that leads to a consumer of the compressed air proceeds from the annular chamber; wherein the stator is connected, in a region of the rotary feedthrough, to a control line; wherein a switchable non-return valve disposed in the annular chamber is formed with blocking elements extending within the annular chamber concentrically to the rotational axis of the rotor that are moved into an open position by an actuating element; and wherein the actuating element is displaced from the stator in a direction of the blocking elements.
