Abstract:
A backfeed stage of a radial turbo fluid energy machine for deflecting a flow direction of a process fluid issuing from a rotor, rotating around an axis, from the radially outward to the radially inward, having a backfeed duct which has three adjacent sections in the flow direction, wherein a first section is designed for conducting the process fluid radially outward, wherein a second section is designed for deflecting the process fluid from radially outward to radially inward direction, wherein a third section is designed for conducting the process fluid radially inward, wherein the second section and third section, or only the third section, have/has first guide vanes which define flow passages of the backfeed duct in relation to each other in the circumferential direction.

Claim (Index 9):
The backfeed stage as claimed in  claim 7 ,\n wherein a bend length in the circumferential direction of the distance between the two trailing edges of adjacent first guide vanes is divided by the radial line through the leading edge of the second guide vane which is arranged between the two first guide vanes in the circumferential direction into a pressure-side section (PSD) and a suction-side section (SSD), wherein\n 0.2<SSD/BLD<0.4 applies.
