Abstract

A supercharger arrangement, having a first rotor assembly, including a first compressor with a first compressor inlet and a first compressor outlet, and a second compressor with a second compressor inlet and a second compressor outlet. The supercharger arrangement also having a second rotor assembly, including a third compressor with a third compressor inlet and a third compressor outlet, and a fourth compressor with a fourth compressor inlet and a fourth compressor outlet; and a first inter-stage conduit that communicates the first compressor outlet with the fourth compressor inlet so that flow from the first compressor feeds into the fourth compressor.

5. The supercharger arrangement according to claim 1, wherein said first compressor has an axial compressor inlet.

6. The supercharger arrangement according to claim 1, wherein said first compressor has a radial compressor outlet.

7. A supercharger arrangement, comprising:

8. The supercharger arrangement according to claim 7, including a heat exchanger in communication with said first inter-stage conduit and said second inter-stage conduit.

9. The supercharger arrangement according to claim 8, wherein said first compressor and said third compressor are first stage compressors, and said second compressor and said fourth compressor are second stage compressors.

10. The supercharger arrangement according to claim 8, wherein said first compressor and said second compressor are first stage compressors, and said third compressor and said fourth compressor are second stage compressors.

11. A supercharged engine, comprising

12. The supercharged engine according to claim 11, including a second inter-stage conduit fluidly connecting a compressor outlet of said second compressor and a compressor inlet of said third compressor.

13. The supercharged engine according to claim 12, including a heat exchanger connecting with said first inter-stage conduit and said second inter-stage conduit.

14. The supercharged engine according to claim 13, wherein said heat exchanger has a rectilinear core.

15. The supercharged engine according to claim 13, wherein said heat exchanger is connected with a coolant source.

16. A method of compressing gas, comprising:

17. The method according to claim 16, including moving the first gas out of a housing of the first compressor.

18. The method according to claim 16 wherein said driving step includes connecting said first compressor and said second compressor to a turbine driven by exhaust gas.
