Abstract

The disclosure illustrates an exhaust gas turbine and compressor system for use with a pneumatic conveyor where the exhaust gas is supplied by an internal combustion engine. The engine utilizes a variable geometry turbine device for changing the torque characteristics of the turbine so as to vary the mass flow of air from the compressor driven by the turbine. As a result, the compressor output will be sufficient to supply air to the engine or to the pneumatic conveyor system while the engine is naturally aspirated. A diverter valve is provided for selectively directing air from the outlet of the compressor either to the air intake of the engine or the pneumatic conveyor.
