Abstract:
PCT No. PCT/DE96/02170 Sec. 371 Date May 13, 1998 Sec. 102(e) Date May 13, 1998 PCT Filed Nov. 12, 1996 PCT Pub. No. WO97/18406 PCT Pub. Date May 22, 1997A device for converting a rotary motion into an axial motion comprises an outer tube (10) with internal contours (10a), an inner shaft (11) with head (11a) with external contours (11b), an inner chamber (R) formed between tube (10) and shaft (11) and a plurality of roller elements (12) arranged in the inner chamber (R) and around the head (11a), which are in active engagement with at least one contour with the internal contour (10a) of the tube (10) and the external contour (11b) of the head (11a), whose position can be adjusted essentially by rotation relative to the roller elements (12). The shaft (11) is surrounded by a tubular element (14) arranged coaxially with respect to the central axis (a-a) of the shaft, which moves translationally relative to the tube (10) when the device is actuated. By this the device is protected in a most simple way from exterior influences: (FIG. 2).
