Definitions
- the separating gap 8 can also be dimensioned such that the calibration pressure P ⁇ is not sufficient to drive the section 15 into the separating gap 8 or to separate the section 15. In this embodiment, the internal high pressure is then increased accordingly via the calibration pressure P ⁇ for the separation process.
