Centrifugal compressor for a turbocharger

摘要

The compressor (1) has a compressor wheel (4) for conveying and compressing a gas. The compressor has an axial inlet side (7) and a radial outlet side (8). The compressor wheel is arranged in a compressor wheel area (3) that extends from the axial inlet side to the radial outlet side. An inlet channel (10) guides to the axial inlet side of the compressor wheel. A recirculation path (12) opens into the inlet channel and the compressor wheel area. A control device (15) changes the flowable cross section of the recirculation path. An independent claim is also included for a method for operating a radial compressor.
