Abstract

Official abstract text for this publication.

A compressor of an exhaust-gas turbocharger has a compressor housing in which a compressor wheel is arranged. The compressor housing has an inlet region. A contour ring is arranged in the compressor housing between the inlet region and the compressor wheel. The contour ring, together with an adjacent wall of the compressor housing, delimits a circulation chamber which has a first connecting opening facing toward the inlet region and a second connecting opening adjacent to the compressor wheel. An exhaust-gas recirculation device has an inlet line which is arranged in the compressor housing and which opens out into the circulation chamber.
