In a compressor of a turbocharger of an internal combustion engine comprising a housing with an inflow channel; a compressor impeller arranged in the inflow channel; and a bypass channel which has a first flow opening upstream of the compressor impeller inlet, a second flow opening downstream of the compressor impeller inlet and an axial annular chamber which connects the first and the second flow openings. An axial vane structure is provided in the axial annular chamber of the bypass channel, which imparts a swirl direction corresponding to that of the air mass flow in the inflow channel to the air mass flowing through the bypass channel from the second to the first flow opening.
