Abstract:
A turbocharger comprising:a rotor rotatable on an axis and including coaxial turbine and compressor wheels;a turbine inlet means configured to conduct engine exhaust gas to adjacent the turbine wheel;an exhaust duct means configured to conduct turbine exhaust gas from the turbine;a turbine nozzle ring defining an annular passage having an inlet end positioned to receive exhaust gas from the turbine inlet means, an outlet end closely surrounding the turbine wheel and stator blades between the ends for directing exhaust gas angularly against energy converting blades of the turbine wheel;the nozzle ring outlet end including at least three radial guides centered on the axis and engaging radial guide means connected with the exhaust duct to maintain axial alignment of the nozzle ring with the axis of the rotor; andseal means at inner and outer edges of the nozzle ring inlet end to seal the edges against leakage of pressurized exhaust gas.
