Abstract:
The invention relates to a device and method for the defined longitudinal shifting of an adjusting device which rotates along in a drive shaft, along the center axis of the drive shaft. The solution according to the invention is characterized in that a working chamber (12) is arranged at the opposite end of the drive shaft (1), into which working chamber a passage hole (7) arranged in the drive shaft (1) opens, wherein a working piston (13) that operatively connects to the working chamber (12) is arranged in such a way that, in the event of a pressure build-up in the working chamber (12), the adjusting device (2) is variably moved against the spring force of a restoring spring (10) by means of a radial piston pump according to the invention that is arranged on the drive shaft (1).
