  • the pressure piston 24 has not yet moved relative to the stationary housing 22 during this engagement process, but only relative to the lock chamber 23.
  • the working body 7 is now directly in front of the still closed lock flap 27.
  • Both the piston rod 32 of the lock chamber 23 and the inner piston 30 have thereby also been moved in the direction of the drive piston, the drive piston also having a smaller distance from the container 2 due to the translation has traveled.
  • the slide 31 is closed, the inner piston 30 only moving up to the slide 31 in the direction of the drive piston.
  • the two mirror-symmetrically arranged insertion devices are designed and connected via hydraulics in such a way that the lock chamber and the pressure piston perform reciprocating movements as well as relative movements to one another, which ultimately make it possible for the working bodies to move into the working position after the pressure has been equalized during the displacement and after the lock flaps have been opened To be able to introduce liquid.
  • This work process is supported by the skillfully translated pressure force of the corresponding liquid column, the other insertion device arranged in mirror symmetry, in particular its lock chamber, lock flaps if closed and pressure piston if open, and also supported by an externally motor-driven working piston.
