摘要

Compressor (30) for a turbocharger (1) of an internal combustion engine, comprising - a compressor housing (31), - a compressor wheel (13) which is arranged in the compressor housing (31) in a rotationally fixed manner on a rotor shaft (14), - one in the compressor housing (31) ) arranged air supply channel (36) for guiding a fresh air mass flow (FM) to the compressor wheel (13), - a first and a second spiral channel (50, 51) each arranged in the compressor housing (31), each of which is arranged downstream of the compressor wheel (13) for receiving of air mass flow (LM) conveyed by the compressor wheel (13) are arranged and each have an air discharge duct (33), - a return duct (52) which fluidly couples the first spiral duct (50) to the air supply duct (36), an exhaust gas recirculation duct ( 54) is fluidly coupled to the return duct (52), and a blocking device (53) which is between a closed position in which the return duct (52) is closed and the air discharge duct (33) of the he most spiral channel (50) is released, and an open position in which the return channel (52) is released and the air discharge channel (33) of the first spiral channel (50) is closed, adjustable.
