A bearing bush of a turbocharger for radially mounting a shaft of the turbocharger. The bearing bush on an inner surface facing the shaft to be mounted, which forms a running surface of the bearing bush, has a microstructuring of multiple cup-shaped recesses at least in sections. The recesses have a maximum depth.

Bearing bush of a turbocharger and turbocharger

A radial compressor of an exhaust gas turbocharger, with a rotating impeller, a fixed housing; a main flow passage defined by the housing for feeding a medium to be compressed towards the impeller; a secondary flow chamber arranged radially outside the main flow passage, which is separated from the main flow passage by a contour wall and is connected to the main flow passage via a secondary flow opening; struts extending in the secondary flow chamber, via which the contour wall is connected to the housing. The struts are curved having a first connecting section of the contour wall that extends in the radial direction and a second connecting section on the housing that extends in the axial direction.

Radial compressor

A radial compressor, with a rotor-side impeller, a stator-side housing, an inflow passage via which medium to be compressed can be fed to the impeller in the axial direction, a diffuser via which compressed medium can be conducted in the radial direction away from the impeller in the direction of a spiral housing section of the housing The diffuser radially outside in a transition region to the spiral housing section has an enlarging flow cross section.
