- This may be provided, for example, at 0 ° C at 3000 bar (corresponding to point 37 in Figure 3), or at 20 ° C at 4000 bar (corresponding to point 38 in Figure 3).
- the CO2 medium provided in this way is guided through the first supply line 11 into the first supply port 31 through first transition point 6, in which a liquid jet of the cutting medium is produced at a lower pressure level.
- the state of the cutting medium after emerging from the first transition point 6 is shown in the figure 3 by the point 39. There is thus a transition from point 37 to 39 or from point 38 to point 39.
- the solid CO 2 particles are supplied to this liquid cutting medium as an abrasive. These already have an output that is suitable for jet cutting. The effect may occur that the abrasive particles increase on the way through the focusing tube 9 due to the attachment of freezing liquid cutting medium.
- an operating point at -57 ° C and 7 bar pressure can be set, corresponding to the point 39 in Figure 3.

- the phase transition (liquid to gaseous or solid to gaseous) takes place after completion of the cutting process after separation and cooling of the cutting region of the workpiece 4.
- only gaseous carbon dioxide remains over from the cutting jet 2.
- a residue-free jet cutting is possible.
- FIG. 4 shows a further embodiment of the jet cutting device, wherein a detailed representation similar to FIG. 2 is used.
- the cutting head 3 has, in the region of the outlet pipe 9, a fourth feed circuit 56 and as a further option a fifth supply port 57 on.
- the fourth supply port 56 is connected via a first pressure reducer 54 via lines 51, 52 with a pressurized gas supply, for example with the pressurized device 22 or the compressed gas supply 23.
- the fifth supply port 57 is connected via a second pressure reducer 55 via lines 51, 53 with a Compressed gas supply connected, for example, with the device under pressure 22 or the compressed gas supply 23rd
- a pressure gradient is to be created with respect to the second supply port 32 or the expansion chamber 7.
- the pressure present at the fourth supply port 34 should be slightly lower than the pressure present at the second transfer port 8.
- a pressure reduction is required if both bodies are fed from the same pressure reservoir, as shown in FIG.
- the first pressure reducer 54 with respect to the fourth supply port 56 and the second pressure reducer 55 with respect to the second supply port 57 serve for this purpose.
- the pressure reducers 54, 55 can be designed as a throttle or diaphragm with a fixed or adjustable cross section.
- the fourth supply port 56 Via the fourth supply port 56, only a slightly lower pressure than at the transition point 8 is generated. Due to this slight pressure difference, eg in the range of 0.1 bar, the liquid cutting medium mixed with the abrasive can be accelerated up to the fourth supply port 56 without a phase transition taking place, ie the liquid cutting medium remains in the liquid phase. Only after the fourth supply connection 56 can a transition of the liquid cutting medium into the gaseous phase take place. If the fifth supply port 57 is not provided, this can be done simply by increasing the pressure downstream of the fourth supply port 56 to the atmospheric level in the region of the exit point 10.
- the fifth supply port 57 If the fifth supply port 57 is present, it can be fed there by feeding Further, in this case considerably lower pressure value than at the fourth supply port 56, the transition into the gaseous phase can be controlled even more precisely. Thus, for example, if a pressure of 15 bar is present at the transition point 8, a pressure of 5 bar can be fed via the fifth supply port 57.
- the fourth supply port 56 is advantageously, in relation to the longitudinal extent L of the outlet tube 9 between the transition point 8 and the exit point 10, arranged in the lower half of the longitudinal extent L, e.g. at the transition to the lower third. In this way, a relatively long acceleration distance for the liquid cutting medium is provided in combination with the abrasive, in which this can be accelerated in a defined manner without gaseous turbulence.
