ABSTRACT:
A turbocharger comprises a compressor housing, a turbine housing, and a central housing with a shaft rotatably supported therein. The shaft supports on its respective opposite ends a compressor wheel and a turbine wheel that are rotatably disposed in the compressor housing and the turbine housing, respectively. The central housing has a large water jacket near the turbine housing and substantially coextensive therewith for storing cooling water to cool bearings which support the shaft. The turbine housing accommodates a shroud including a vane holder on which fixed and movable vanes are alternately supported for directing exhaust gases to the turbine wheel through variable restrictions. The vane holder or base plate has a radially outer flange and an annular boss which position the shroud axially and radially with respect to the central housing.
