摘要

A threaded spindle (TS) as an operating device fits in a casing and can be fed forward on-axis against the casing. A drive motor (14) causes the TS to be fed forward by means of a spindle nut (13) placed around the TS and fitted to rotate on bearings in the casing. A stator (15) and a rotor (16) for the drive motor fit in the casing. The spindle nut fastens concentrically on the rotor.
