IMPROVED NOZZLED TURBINE

A turbine (120) includes a turbine housing (215) having two gas passages (236) of substantially the same flow area. A nozzle ring (238) is disposed in the housing (215) and around the turbine wheel (212). The nozzle ring (238) includes first and second outer rings, and an inner ring (242) disposed b...

Summary:A turbine (120) includes a turbine housing (215) having two gas passages (236) of substantially the same flow area. A nozzle ring (238) is disposed in the housing (215) and around the turbine wheel (212). The nozzle ring (238) includes first and second outer rings, and an inner ring (242) disposed between the first and second outer rings. First and second pluralities of vanes (246) are disposed between the rings. The second outer ring (243) has a thicker cross section than the first outer ring (243) such that a larger flow area is created between the first outer ring (243) and the inner ring (242) than a flow area created between the second outer ring (243) and the inner ring (242). L'invention porte sur une turbine (120), qui comprend un carter de turbine (215) comportant deux passages de gaz (236) ayant sensiblement la même surface d'écoulement. Une bague de buses (238) est disposée dans le carter (215) et autour de la roue de turbine (212). La bague de buses (238) comprend des première et seconde bagues externes, et une bague interne (242) disposée entre les première et seconde bagues externes. Des première et deuxième pluralités d'aubes (246) sont disposées entre les bagues. La seconde bague externe (243) a une section transversale plus épaisse que la première bague externe (243), de telle sorte qu'est créée une surface d'écoulement entre la première bague externe (243) et la bague interne (242) plus grande qu'une surface d'écoulement créée entre la seconde bague externe (243) et la bague interne (242).
