摘要
A backfeed stage of a radial turbo fluid energy machine having a backfeed channel extending annularly about an axis and four sections adjacent in the flow direction through which process fluid flows. A first section conducts the process fluid radially outward; a second section deflects the process fluid from radially outward to radially inward; a third section conducts the process fluid radially inward; a fourth section redirects the process fluid in the axial direction; the third section has first guide vanes defining flow channels of the backfeed channel in relation to each other in the circumferential direction; the backfeed stage has second guide vanes downstream of the first guide vanes defining the flow channels of the backfeed channel in relation to each other in the circumferential direction. The first guide vanes are arranged only in the third section, the second guide vanes are arranged only in the fourth section.
