An engine supercharger is modified to include an auxiliary turbine downstream from the main turbine wheel. The main shaft of the supercharger is tubular (hollow) to accommodate a second shaft. The opposite ends of the second shaft are suitably connected to the auxiliary turbine and an auxiliary fan that is located upstream from the main compressor wheel within the supercharger. An air-collection chamber of scroll-like configuration is arranged between the auxiliary fan and compressor wheel to receive air discharged from outer tip areas of the fan blades.
An engine supercharger comprising a turbine housing, a main turbine wheel of the radial-inflow type located within said turbine housing, a compressor housing having an air entrance passageway (38), a compressor wheel of the centrifugal type located within said compressor housing, a main shaft (18) of annular construction interconnecting said turbine wheel and said compressor wheel whereby the two wheels rotate as a unit, an auxiliary turbine wheel of the axial flow type located downstream from the main turbine wheel, a fan of the axial flow type located ...
