Abstract
A variable geometry turbocharger comprises a turbine wheel () mounted within a turbine housing () on one end of a turbocharger shaft () for rotation about a turbocharger axis. The turbine housing () defines an annular turbine inlet () around the turbine wheel (). A compressor wheel () is mounted within a compressor housing () on the other end of the turbocharger shaft (). Turbocharger shaft bearing assemblies () are located within a bearing housing () connected between the turbine housing () and the compressor housing (). A variable geometry mechanism () is provided for varying the size of the annular turbine inlet (). The variable geometry mechanism is actuated by a tubular linear electric motor comprising a fixed annular stator ring () and an axially moveable annular forcer ring (), arranged coaxially about the turbocharger axis.
