Abstract: A turbocharger comprises a center housing, and a shaft positioned therein having a first end and a second end. A turbine housing is attached to one side of the center housing and has a turbine wheel disposed therein that is coupled to the first end of the shaft. A first variable geometry member is disposed within the turbine housing between an exhaust gas inlet and the turbine wheel. A compressor housing is attached to another side of the center housing opposite the turbine housing, and includes a compressor impeller disposed therein. The compressor impeller is coupled to the second end of the shaft. A second variable geometry member is disposed within the compressor housing, and is interposed between an air outlet and the compressor impeller. An actuator assembly is disposed within the turbocharger and is connected to both of the variable geometry members to provide simultaneous actuation of the same.
