Abstract
In an exhaust turbine of a turbocharger with a rotor mounted rotatably in a turbine casing having a spiral inlet duct with a guide vane structure including guide vanes arranged around the rotor and extending essentially tangentially to an outer and inner imaginary circular surface areas in the inflow zone and, respectively, the outflow zone of the guide vane structure, at least the trailing edges but preferably also the leading edges of the guide vanes extend at an angle to an axial line of the imaginary circular surface areas, thereby providing for a uniform loading of the rotor.
Claims4
An exhaust turbine for a turbocharger comprising a turbine casing with a spiral inlet duct, a rotor mounted rotatably in said turbine casing, a guide vane structure with guide vanes arranged in said inlet duct so as to surround the rotor, said guide vanes extending essentially tangentially to an outer and an inner imaginary circular surface in an inflow area and an outflow area of said guide vane structure, said guide vanes having leading edges and trailing edges with at least said trailing edges extending at an angle to axial lines of said imaginary circular surfaces.
