Abrégé

Centrifugal action-reaction turbine (11) comprising a support structure (13) integral with a stator (15), connecting means (17) for a rotor (19), a rotor (19) rotatably supported by said connecting means (17), and a feed system (21) for drawing a fluid from a penstock, wherein the feed system (21) is spatially located at the center of the rotor (19), the rotor (19) comprises at least one radial channel (45) which is radially arranged around the feed system (21) and within which the fluid flows, wherein the at least one radial channel (45) comprises, with respect to the feed system (21), a proximal end (75) in flow communication with the feed system (21) and a distal end (77) comprising a nozzle (55) and being in flow communication with said nozzle for the exit of the fluid from the rotor (19), and wherein, at the nozzle (55), a plurality of fixed tabs (57) are provided on the stator (15).
