Radial Compressor

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

• An impeller configured to rotate;
• 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, 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;
• struts that extend in the secondary flow chamber, via which the contour wall is connected to the housing;
• wherein the struts are curved such that as seen in a meridional section a first connection section of a respective strut on the contour wall extends in a radial direction or predominantly in the radial direction and a second connection section of the respective strut on the housing extends in an axial direction or predominantly in the axial direction.
