  • the longer screws 31 b are inserted from the side of a plane surface 33 b of the cylinder cover 33 through through holes and screwed into corresponding threaded holes with internal thread in the upper part of the adapter component 11.
  • the flat surface 33b is the flat surface 33a aligned in parallel.
  • the through-holes in the cylinder cover 33 and the corresponding screw-in holes in the upper part of the adapter component 11 correspond in their relative position or their hole pattern to the hole pattern 24 in the plane surface 25a and the hole pattern 26 in the lower part of the adapter component 11 on the main sides 29 and 34th
  • a hydraulic coupling between the translator part 9 and the working part is realized by hydraulic fluid from the translator part 9 via an opening 35 in the cylinder cover 33 and further via the opening 30 in the main side 34 at a corresponding stroke movement of the booster and working piston into a connecting line within the adapter component 11 and from there to the opening 28 in the cylinder cover 25 of the working part 8 can flow into a hydraulic space in the working part 8.
  • the relative position between the translator part 9 and the working part 8 can be chosen variably.
  • the adapter component 11 can, starting from a mounting position z. B. according to FIG. 11 be mounted offset at a square hole pattern or square arrangement of the screw by 90, 180 and 270 degrees about a central axis of the opening 28, whereby the translator part 9 is changed according to its orientation to the working part 8.
  • the translator part 9 can be screwed offset to the central axis of the opening 30 in the adapter component 11 by 90, 180 and 270 degrees.
