Abstract

Disclosed is a turbine arrangement for a supercharging device. The turbine arrangement comprises a turbine housing, a turbine wheel and a guide device. The turbine housing defines a turbine spiral and a turbine outlet. The turbine wheel is arranged in the turbine housing between the turbine spiral and the turbine outlet. The guide device comprises a carrier ring and multiple guide blades. The guide blades are arranged on the carrier ring fixedly in a predetermined orientation. The guide device is arranged in an inflow channel between the turbine spiral and the turbine wheel such that, during operation, fluids are conducted from the turbine spiral through the inflow channel over the guide blades onto the turbine wheel.
