Patent ID: 7866226

Claim:
An electromotive actuator for deflecting a mechanical part, the actuator comprising: a deflection gear including a ball-ramp adjustment device having a rotatable component acting directly or indirectly on the mechanical part and a non-rotatable component; and an electric motor having a rotor, wherein the rotatable component is non-rotatably connected to the rotor so as to be linearly moveable relative to the non-rotatable component between a first position and a second position; wherein the ball-ramp adjustment device includes a plurality of adjusting rings disposed axially adjacent to each other, a rotatable seat ring disposed at a first axial end, and a non-rotatable seat ring disposed at a second axial end opposite the first axial end; wherein each of the plurality of adjusting rings has guide tracks on both sides and wherein the rotatable seat ring and the non-rotatable seat ring each has guide tracks on one side, such that each corresponding pair of axially facing guide tracks is configured to receive an associated ball.
