  • Multistage turbocompressor with multiple shafts
    Patent number: 4219306
    Abstract: The impellers of two rotary compressors are respectively fixed to the opposite ends of each shaft of a plurality of shafts, the compressors being connected in succession by connecting pipes to constitute a single multistage combination of the compressors in successive compression stages, the impeller of the preceding stage of the impellers on each shaft having a gas exit flow angle which is less than that of the impeller of the succeeding stage thereby to cause the specific speed of each impeller to be at its optimal value.
