摘要: The invention relates to a wheel (R) of the Francis type that comprises ring ( 1 ) with revolution symmetry about rotation axis (Z) (R), and curved blades 21, 22 connected each having an outer peripheral edge 212, 222 inner central 211, 221 ). connection points (B 21 , B between edges are located on same circle (C 20 centered (Z). (A A at least two distinct circles C (D D
