Definitions
- piston rods may be deflected so that their outer end lies parallel with the cartridge next to this cartridge and not in axial continuation thereof.
- the tape is made of a plastic so as moulded polypropylene and the needed stiffness is obtained by giving the tape a curved cross section and by beads along the lateral edges of the tape.
- the curved shape of the cross section corresponds to the curving of the inner wall of the cartridge so that the tape may abut this inner wall in its full width.
- Figure 3 shows another embodiment of a deflected piston rod according to the invention
- Figure 4 shows still another embodiment of a deflected piston rod according to the invention.
