Definitions

  • the OMPI Hose line is executed.
  • the first variant enables the entire drive to be shortened to almost half the length.
  • the second variant opens up the possibility of a spatially further separated arrangement of the two cylinder housings, so that only the working cylinder housing must be installed in the machine in question, which requires such an output.
  • the push-in space 13 is connected via a channel 14 to the front opening of the cylinder element 7.
  • a stepped working piston 15,. Moves in this cylinder jacket and in the cylinder jacket 6.
  • FIG. 3 shows another embodiment of a working cylinder housing, which could also be used together with the booster cylinder housing 24 according to FIG. 2.
  • a stroke limitation and a path-dependent switch from rapid traverse to power stroke could be applied.
