Abstract

a. Système d'inversion d'aubes, pour turbines réversibles tournant dans un seul sens. b. Système caractérisé en ce que les aubes tournant autour des pivots dans un de leurs points neutres portent une sur l'autre, forment un canal légèrement courbé conduisant le liquide dans un sens, pendant que, dans les points neutres opposés, ensemble avec les aubes fixes du diffuseur spiral et les aubes directrices, elles forment plusieurs canaux, qui inversent le sens du courant du liquide. c. L'invention s'applique aux turbines réversibles tournant dans un seul sens.at. Vane reversing system, for reversible turbines rotating in one direction. b. System characterized in that the vanes rotating around the pivots in one of their neutral points bear on each other, form a slightly curved channel leading the liquid in one direction, while, in the opposite neutral points, together with the fixed vanes of the spiral diffuser and the guide vanes, they form several channels, which reverse the direction of the liquid flow. vs. The invention applies to reversible turbines rotating in one direction.
