ABSTRACT:
A one-piece housing casting comprising a hub adapted to receive a turbine shaft therethrough and a radially extending flange on the outer periphery of the hub. The flange includes radially aligned annular surface portion and means for spacing the surface a predetermined distance from a radially aligned housing wall close to the outlet of the centrifugal compressor. The flange also includes an axially extended portion having an axially extended surface and means for spacing the surface away from an axially extending surface on a turbine housing wall to define a passage therebetween. Preferably, the means for spacing the walls apart from the turbine housing wall surfaces comprise diffuser vanes integrally formed on the radially and axially aligned surfaces of the flange of the diffuser member.
