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.
Claims18
A supercharger arrangement, comprising:
- a first compressor and a second compressor in parallel fluid relation and rotatably coupled by a first rotor assembly;
- a third compressor and a fourth compressor in parallel fluid relation and rotatably coupled by a second rotor assembly;
- and
- a first inter-stage conduit fluidly connecting a compressor outlet of said first compressor and a compressor inlet of said fourth compressor.
A supercharger arrangement, comprising:
- a first rotor assembly including a first compressor and a second compressor;
- a second rotor assembly including a third compressor and a fourth compressor,
- a first inter-stage conduit fluidly connecting a compressor outlet of said first compressor and a compressor inlet of said fourth compressor;
- and
- a second inter-stage conduit fluidly connecting a compressor outlet of said third compressor and a compressor inlet of said second compressor.
A supercharged engine, comprising
- a combustion chamber;
- an intake conduit fluidly connecting with said combustion chamber;
- at least one exhaust conduit in fluid communication with said combustion chamber;
- a first rotor assembly including a first compressor and a second compressor;
- a second rotor assembly including a third compressor and a fourth compressor;
- a first turbine being connected with said first rotor assembly and fluidly connecting with one of said at least one exhaust conduit;
- a second turbine being connected with said second rotor assembly and fluidly connecting with one of said at least one exhaust conduit;
- and
- a first inter-stage conduit fluidly connecting a compressor outlet of said first compressor and a compressor inlet of said fourth compressor.
A method of compressing gas, comprising:
- compressing a first gas in a first compression stage using a first compressor;
- further compressing the first gas in a second compression stage using a fourth compressor;
- compressing a second gas in a first compression stage using a third compressor;
- further compressing the second gas in a second compression stage using a fourth compressor;
- driving said first compressor and said second compressor;
- and
- cooling said first gas between the first and second compression stages and cooling said second gas between the first and second compression stages.
