From the first module 35, the gas mixture is supplied to the underlying second module 34, which has a cooling device.
- the mixture flows through the second module 34 to the central module 33, from where it flows laterally into the compression devices 2, 2 ', the so-called high-pressure compressors (the two high-pressure compressors 2, 2' are also vibration-decoupled via compensators 43, 43 'to the separate module 10 ).
- the compression of the mixture to the final pressure.
- the next station is the module 32, which has another mixture cooler for cooling the mixture. From the module 32 is now a diversion into the central module 33, from where the actual supply to the engine 1 via the line 27 takes place.

In the compression devices 3, 3 'now flows uncompressed fuel / air mixture and is compressed in the low pressure compressor. From there, the mixture flows through the module 35 to the first mixture cooler, which is arranged in the module 34.
- FIG. 2b now shows the side view. Again, the gas flow from the uncompensated fuel / air mixture on the low-pressure compressor 3 to the module 35 and from there to the module 34 with mixture cooler can be seen. From there, the gas mixture flows to the central module 33, where a deflection of the mixture takes place. The gas mixture flows perpendicular to the image plane out of the image plane or into the image plane into the respective high-pressure compressor 2, 2 '. From there, the diversion takes place via the lines 30, 30 ', which are not shown for the sake of clarity, to the module 31, where an opening can be seen.
