Exhaust-gas turbocharger in an internal combustion engine

Abstract

An exhaust-gas turbocharger in an internal combustion engine has a turbine and a compressor which is driven by the turbine and contains, in a compressor flow duct, a compressor impeller. A bypass to the compressor impeller communicates with the inflow duct via a first flow opening and, via a second flow opening, communicates with the compressor outflow region downstream of the outlet edge of the compressor impeller. A shutoff element which may be adjusted between a closing position and an opening position is provided in the bypass for the purpose of variably setting the effective flow cross-section of the bypass. The adjustable shutoff element is arranged in the second flow opening to the compressor outflow region.
