The invention provides a turbocharger for use with an internal combustion engine and includes a compressor for supplying air to the engine and a turbine for receiving driving exhaust gas from the engine. The turbine has a shaft integrally attached thereto with which the turbine rotates. The compressor is fitted on the turbine shaft for rotation with the turbine. The shaft is rotatively supported by ball bearing assemblies such that the compressor and turbine are overhung to one side of the bearing assemblies with the turbine separated from the bearing assemblies by the compressor. As a result of this arrangement, the bearing assemblies are removed from the turbine and the intense heat to which the turbine is subjected. This makes possible the use of limited lubrication for the bearing assemblies. The use of ball bearings also provides better control over the radial and axial movement of the turbine and compressor and permits reduced blade tip clearances. The turbocharger includes a turbine nozzle having a plurality of nozzle vanes spaced circumferencially about the turbine and in the inlet through which exhaust air from the engine is received into the turbine. A control linkage is positioned intermediate of the compressor and turbine and controls the position of the nozzle vanes to vary the flow of exhaust gases into the turbine. The variable area turbine nozzle control linkage includes a control ring having an outer ring moveable angularly relative to an inner ring. An actuation lever is rotatable with each vane and has one end engaged in the outer ring of the control ring. A control rod is attached to one of the actuation levers and structure is provided for selectively moving the control rod to pivot the actuation lever attached thereto. This in turn rotates the outer ring of the control ring thereby pivoting each of the actuation levers and the vanes attached thereto.
