A radial compressor having an impeller having a housing with a radially outer and a radially inner insertion section a main flow channel for suppling a medium towards the impeller, a circulation chamber radially outside of the main flow channel separated from the main flow channel by a contour wall and connected to the insertion section via struts. The main flow channel is delimited by the contour wall and by a first segment of the insertion section. The struts engage with a second segment of the insertion section. The second segment of the insertion section engages with a downstream end of the first segment of the insertion section. The upstream end of the first segment of the insertion section protrudes freely in the direction of the contour wall. The first segment of the insertion section has a constant thickness.

Radial compressor

A radial compressor of an exhaust gas turbocharger, with a rotating impeller, a fixed housing; a main flow passage defined by the housing for feeding a medium to be compressed towards the impeller; a secondary flow chamber arranged radially outside the main flow passage, which is separated from the main flow passage by a contour wall and is connected to the main flow passage via a secondary flow opening; struts extending in the secondary flow chamber, via which the contour wall is connected to the housing. The struts are curved having a first connecting section of the contour wall that extends in the radial direction and a second connecting section on the housing that extends in the axial direction.
