Compressor of an exhaust-gas turbocharger

Abstract

A compressor ( 8 ) of an exhaust-gas turbocharger ( 1 ), having a compressor wheel ( 11 ) which can be driven in a compressor wheel direction of rotation (VR); having a compressor housing ( 10 ) in which the compressor wheel ( 11 ) is arranged, as viewed in the flow direction of the inducted air, between a preferably tubular compressor inlet ( 12 ) and a compressor outlet ( 13 ), and having an overrun air recirculation valve inflow duct ( 14, 15 ) which runs in the compressor housing ( 10 ) from the compressor outlet ( 13 ) to the compressor inlet ( 12 ), wherein the inflow duct ( 14, 15 ) opens into the compressor inlet ( 12 ) substantially in the circumferential direction with respect to the inner diameter (D I ) of said compressor inlet ( 12 ).

1 . A compressor ( 8 ) of an exhaust-gas turbocharger ( 1 ),
 having a compressor wheel ( 11 ) which can be driven in a compressor wheel direction of rotation (VR);   having a compressor housing ( 10 ) in which the compressor wheel ( 11 ) is arranged, as viewed in the flow direction of the inducted air, between a compressor inlet ( 12 ) and a compressor outlet ( 13 ), and   having an overrun air recirculation valve inflow duct ( 14 ,  15 ) which runs in the compressor housing ( 10 ) from the compressor outlet ( 13 ) to the compressor inlet ( 12 ), wherein   the inflow duct ( 14 ,  15 ) opens into the compressor inlet ( 12 ) substantially in the circumferential direction with respect to the inner diameter (D I ) of said compressor inlet ( 12 ).   
     
     
         2 . The compressor as claimed in  claim 1 , wherein the inflow duct ( 15 ) opens into the compressor inlet ( 12 ) in such a way that the inflow of air takes place in the direction of rotation (VR) of the compressor wheel ( 11 ). 
     
     
         3 . The compressor as claimed in  claim 1 , wherein the inflow duct ( 14 ) opens into the compressor inlet ( 12 ) in such a way that the inflow of air takes place counter to the direction of rotation (VR) of the compressor wheel ( 11 ). 
     
     
         4 . The compressor as claimed in  claim 1 , wherein the inflow duct ( 14 ) opens into the compressor inlet ( 12 ) in such a way that the inflow of air has an axial component in the flow direction. 
     
     
         5 . The compressor as claimed in  claim 1 , wherein compressor inlet ( 12 ) is tubular.
