TURBINE HOUSING

摘要

A turbine housing comprises an exhaust port flange, a turbine discharge flange, a crossover flange, and a bearing support ring. The exhaust port flange is configured for mechanically coupling the turbine housing to a mating structure providing a source of working fluid. The turbine discharge flange is configured for mechanically coupling the turbine housing to an exhaust system. The crossover flange is configured for mechanically coupling the turbine housing to a crossover duct. The bearing support ring is configured for mechanically supporting a bearing, on which a turbine output shaft is supported. The turbine housing defines an inlet plenum, a turbine shroud, and a discharge vent. The exhaust port flange defines an inlet port configured to provide fluid communication between the inlet plenum and the source of working fluid. The turbine shroud defines a fluid expansion flow path for expansion of the stream of working fluid.

1. A primary turbine housing comprising:
an exhaust port flange configured for mechanically coupling the primary turbine housing to a primary mating structure for providing a primary source of working fluid; a turbine discharge flange configured for mechanically coupling the primary turbine housing to an exhaust system; a crossover flange configured for mechanically coupling the primary turbine housing to a crossover duct; and a bearing support ring configured for mechanically supporting a bearing, on which a turbine output shaft is supported for rotation about its longitudinal axis; wherein the primary turbine housing defines an inlet plenum, a turbine shroud, and a discharge vent; wherein the exhaust port flange defines a primary inlet port that is configured to provide fluid communication between the inlet plenum and the primary source of working fluid; wherein the primary inlet port is configured to convey a primary stream of working fluid from the primary source of working fluid to the inlet plenum; and wherein the turbine shroud defines a fluid expansion flow path for expansion of a turbine inlet stream between a turbine inlet and a turbine exit, the turbine inlet stream comprising at least a portion of the primary stream of working fluid.
