  • Compressor for an exhaust gas turbocharger
    Patent number: 8388312
    Abstract: A compressor for an exhaust gas turbocharger includes an exhaust gas turbocharger housing having a gas intake port, which substantially radially encloses a gas inflow area. Disposed in the exhaust gas turbocharger housing is a compressor wheel, which can be driven by an exhaust gas turbine. The compressor wheel bounds the gas inflow area in the gas intake port in the direction of flow of a gas. The gas intake port includes indentations on a side of the inflow area. The flow noise in normal operation of the compressor and the acoustic effect in the case of pumping are reduced with the indentations.
