<p>Turbocharger (20), compressor (170) and turbine (172) rotors mounted on a shaft (160) supported by ball bearing assemblies (162, 164) such that the compressor rotor (172) and turbine rotor (170) are overhung to one side of the bearing assemblies with the turbine rotor separated from the bearing assemblies by the compressor rotor. The turbocharger (20) includes a turbine nozzle area (230) having a plurality of nozzle vanes (234) spaced circumferentially about the turbine rotor and in the nozzle area through which exhaust air from the engine is received into the turbine. A control linkage (228) is positioned intermediate of the compressor rotor and turbine rotor and controls the position of the nozzle vanes to vary the flow of exhaust gases to the turbine rotor. A concentrically positioned cylindrical module (60) is supported within the compressor inlet by struts (62) extending from the inlet wall (64) to the module (60) thereby dividing the inlet into more than one inlet passage. In one embodiment of the invention, a second compressor rotor (450) is mounted on the shaft (160) in the compressor rotor (172). In other embodiments of the invention, the turbocharger (20) is modified to function as a turbojet (500, 750) and as a turbofan (650).</p> |
