An impeller wheel assembly (2) for a radial rotating machine, comprises a bladed hub portion (4) of an impeller wheel, with a first radially outward facing, fluid deflecting surface (11) having a curvature profile designed to deflect an axial fluid flow into a radial centrifugal flow, and comprising a deflector portion (3, 14) with a second radially outward facing, fluid deflecting surface (12, 13). The second radially outward facing surface (12, 13) has a curvature profile designed to deflect a radial centripetal fluid flow (28, 29) into an axial fluid flow (26, 25). |
