Abstract (en)
[origin: EP1650402A1] The propulsion device has to be driven through a pilot opening in the wall (3). The forces resulting from the process are guided into a pressure ring (4) located behind the device by threaded pulling bars (7) arranged longitudinally along the outer surface of the device and joined with their outer ends to the wall (3), the pressure ring (4) respectively. A pressure element (5) with a hollow piston can be positioned between the pressure ring (4) and a securing nut (11).
