Abstract: A recirculation stage of a radial turbomachine, the recirculation stage has an inner delimiting contour and an outer delimiting contour. The stator vane stage has stator vanes, wherein a difference between a vane construction angle at the leading edge and a vane construction angle at a downstream position defines a redirection angle for each point on the camber line of a respective profile cross section, wherein the stator vanes extend at least along part of the third section, wherein the trailing edges are arranged in the third section, wherein at the trailing edges in the center of the span width the redirection angle is in each case greater than the average overall redirection angle, wherein at both ends of the span width at in each case at least 10% of the span width in each case the redirection angle is smaller than the average overall redirection angle.
