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.
