Radial compressor

A radial compressor, of an exhaust gas turbocharger, comprising:

• an impeller configured to rotate;
• a fixed housing;
• a main flow passage defined by the housing configured to feed a medium to be compressed in a direction of the impeller;
• a contour wall;
• a secondary flow chamber arranged radially outside the main flow passage, connected to the main flow passage via a first flow opening, which is separated from the main flow passage by the contour wall and which in a region of the impeller is connected to the main flow passage via a secondary flow opening;
• and
• struts that extend in the secondary flow chamber, via which a first connection section of a respective strut is connected to the contour wall and a second connection section of the respective strut is connected to a radially extending portion of the housing whereby the contour wall is connected to the housing;
• wherein the struts are curved such that as seen in a meridional section the first connection section of the respective strut on the contour wall extends in a radial direction or predominantly in the radial direction and the second connection section of the respective strut on the housing extends in an axial direction or predominantly in the axial direction.
