Abstract

A compressor for an internal combustion machine includes a compressor impeller rotatably mounted in a compressor casing. A circumferential step is integrated into a wall which delimits an intake section disposed upstream of the compressor impeller in an operating flow direction of a gas to be compressed. The circumferential step is a mouth-free circumferential step which faces the compressor impeller and delimits a flow cross section. A ratio of a shortest distance between the compressor impeller and the circumferential step to a largest cross-sectional dimension in the flow cross section delimited by the circumferential step is at least 0.5. An exhaust gas turbocharger and an internal combustion machine are also provided.
