Abstract

A turbocharger has a shaft with a rotational axis, a radial/axial turbine wheel which is arranged in a turbine housing and which is connected to the shaft in a non-rotatable manner, and a bearing housing which adjoins the turbine housing and which contains a lateral wall facing the turbine housing. A sub-region of the lateral wall of the bearing housing forms a sub-region of the rear wall of the turbine housing. The sub-region of the bearing housing has two sub-sections, one of which runs diagonally to the rotational axis in an inflow direction of an exhaust gas flow conducted into the turbine housing and the second of which runs in a radial direction relative to the rotational axis of the shaft and parallel to the rear wall of the turbine wheel. The two sub-sections are connected to each other via an exhaust gas flow separation edge of the bearing housing.
