Claim 11:
12. The system according to claim I. wherein the cartridge outer wall is cylindrical on an outside;
wherein the side wall of the support structure comprises a cylindrical outer tube and a hydraulic cushion which rests on an inside, on the outer tube over its entire radial circumference and also at least partly on the support structure front wall, and is filled with a flowable medium; and
wherein the hydraulic cushion is designed and dimensioned in such a way that when the coaxial cartridge is inserted in the support structure, said hydraulic cushion encloses the entire outer wall of said coaxial cartridge and at least part of the cartridge front wall, wherein an inner diameter of the hydraulic cushion, in an unloaded state which prevails before and during insertion of the coaxial cartridge into the support structure, is larger than an outer diameter of the cartridge outer wall by a predetermined annular gap which is twice the width, whereas, in a loaded state which occurs at the start of the pressing-out process and pressing of the cartridge outer wall against the support structure front wall, the hydraulic cushion comes to fit tightly against the entire cartridge outer wall due to an immediate escape of the flowable medium from a front wall portion into a side wall portion.
