ABSTRACT:
This disclosure deals with a centripetal flow turbine housing including an intake opening for receiving a working fluid, a volute which conveys the fluid to a turbine wheel rotatably mounted within the housing, and an outlet opening co-axial with the wheel. A valve is provided adjacent the intake opening, and two intake passages are formed in the housing between the valve and the volute. One of the intake passages is arranged concentrically around the other intake passage, and the intake passages merge ahead of the volute to form generally concentric aspirating nozzles. The valve is adjustable to one position where it directs all of the working fluid through one intake passage, and to a second position where it directs the working fluid through both intake passages. The turbine housing may be used with an internal combustion engine having a divided exhaust manifold to obtain pulse turbine operation, or it may be used with an internal combustion engine such as a two-cycle engine without a divided exhaust manifold to assist in starting and low speed engine performance.
