Abstract
A multistage radial compressor () with at least two compressor stages for compressing a fluid has a compressor housing () in which a flow channel () is formed for the fluid to be compressed; an impeller () with a plurality of impeller vanes () which are arranged in the flow channel () and are rotatable with the impeller () around a driveshaft (A), and a 3D return blading () with a plurality of return vanes () which are fixed with respect to rotation relative to the compressor housing (). The flow channel () has a curved deflecting channel () which is arranged in front of the return vanes () in the flow direction. A vane base () and/or, axially downstream thereof, a vane head () of the return vanes () of the 3D return blading () have/has a curvature, and/or the return vanes () have a first vane angle distribution () at the vane base () and a second vane angle distribution () differing from this at the vane head ().
