Abstract (en)
The centrifugal turbine according to the present invention is essentially characterised in that its rotor (3) possesses on one of its faces a circular groove (11) concentric with it; in that the blades (5) of its rotor are formed by an insert (14) having an anterior face and a posterior face which are mutually parallel, and by a flared foot projecting on the anterior and posterior faces of the corresponding insert, the foot of the blades having a length substantially equal to the width of the groove and a height substantially equal to the depth thereof; and in that sectors (18) fixed in the groove each extend substantially flush with the faces opposite two successive blades, the ends of these sectors being in contact with the parts facing the feet which they cover and which have a shape complementary to their own. <IMAGE>
