Abstract:
1. A compressor for an exhaust gas turbocharger, comprising: an exhaust gas turbocharger housing having a gas intake port substantially radially enclosing a gas inflow area; a compressor wheel disposed in the exhaust gas turbocharger housing, the compressor wheel bounding the gas inflow area in the gas intake port in a flow direction of a gas and being drivable by an exhaust gas turbine; and indentations of the gas intake port located on a side of the gas inflow area, wherein the indentations are radially extending grooves configured as back cuts in the flow direction with gas inlet and outlet regions upstream of the compressor wheel and extend into a wall of the gas intake port to form a void space radially outside of the gas intake port, wherein a cross-section of an opening of the indentation at the gas intake port wall is smaller than a largest cross-section of the void space radially outside the gas intake port wall.
