COMPRESSOR, TURBOCHARGER AND INTERNAL COMBUSTION ENGINE

The invention relates to a compressor (22) comprising a housing (36) which forms a flow chamber in which a compressor impeller (30) is rotatably mounted, and an inlet channel (40) which joins a compressor inlet to the flow chamber. A tubular flow guide element (52) is arranged in the inlet channel (40), said guide element dividing at least one section of the inlet channel (40) into a central flow region (54) and a peripheral flow region (56), the two merging in the flow chamber in the region of the inlet plane (38) of the compressor impeller (30). An exhaust gas recirculation leads into the peripheral flow region (56), and the peripheral flow region (56) can be closed by a closing device (84) in a section upstream of the mouth (72) of the exhaust gas recirculation, and the flow guide element (52) comprises at least one overflow opening (66) in a longitudinal-axially centrally located section. A compressor (22) of said type is characterised in that at least one end section (62) of the flow guide element (52) which is adjacent to the compressor impeller (30) can be longitudinally-axially moved, said end section (62) closing the peripheral flow region (56) in the region of the inlet plane (38) when the flow guide element (52) is in the closed position and is released when it is in the open position.
