Abstract

In a radial compressor, particularly of an exhaust gas turbocharger of an internal combustion engine, having a compressor housing within which a compressor wheel is disposed for compressing air from an inflow channel of the compressor housing and directing the air to an outflow channel of the compressor housing, the compressor housing comprising a bypass channel having a first flow opening upstream of an axial compressor wheel inlet and a second flow opening downstream of the compressor wheel inlet, the compressor housing is configured at least in a flow region upstream of the second flow opening in an asymmetric manner with regard to a rotational axis of the compressor wheel.
