Road is integrated into the turbine casing.
The known multi-stage compression for implementing pressurized air with two or more exhaust-driven turbo-charger exhaust-gas turbo chargers, these exhaust gas turbines
Booster is worked together with the compressor being connected in series, and wherein intercooler is arranged between each compressor.Substantially from US
This scheme known to 2014/0358404 A1.Although a disadvantage is that these schemes are extremely complex and expend structure space.Class
It is to be used to the multi-stag compressor drum on common axle realize each compressor stage, including combination axial compressor like method
Level and radial compressor level.However, herein also especially because the increase length of exhaust-driven turbo-charger exhaust-gas turbo charger and in Package size side
Face and be unfavorable also in terms of rotor dynamics and storage problem.
On the other hand, the T2 of DE 699 14 199 show the pressure turbine of the slow operating with two-stage type compressor, wherein,
