Patent ID: 7824271

Claim:
A device for adjusting the relative angular position of two rotating elements ( 1 , 2 ) interconnected by a transmission element ( 3 ) and connected to a drive structure, including: an electric actuating drive ( 5 ), an actuating shaft ( 4 ) extending between the transmission element ( 3 ) and the electric actuating drive ( 5 ), the actuating drive ( 5 ) comprising a stator ( 5 b ) and a rotor ( 5 a ) axially movable supported and connected to the actuating shaft ( 4 ) for rotation with the actuating shaft ( 4 ) in order to change the relative angular position of the rotating elements ( 1 , 2 ), and biasing means ( 6 ) for axially biasing the rotor ( 5 a ) into engagement with at least one of the rotating elements ( 1 , 2 ), providing thereby for engagement between the actuating shaft ( 4 ) and one of the rotating elements ( 1 , 2 ) of the actuating drive ( 5 ) for interlocking the rotating elements ( 1 , 2 ) in their relative angular position.
