Abstract

L'invention concerne une turbine Francis ou un autre machine présentant une construction selon le principe Francis, comprenant une roue dotée d'aubes, une bâche spirale entourant la roue, un anneau d'entretoises comprenant un nombre donné d'entretoises, et une couronne d'aubes directrices interne présentant des entretoises plus grandes, qui est placée à la suite de l'anneau d'entretoises. L'invention est caractérisée par les éléments suivants : la turbine comprend une couronne d'aubes directrices externe qui est placée avant l'anneau d'entretoises; une partie de l'anneau d'entretoises dotée d'entretoises relativement grandes s'étend sur une partie de la périphérie de la roue en partant du début de la spirale, et une partie de l'anneau d'entretoises dotée d'entretoises plus petites s'étend sur le reste de la périphérie de la roue, jusqu'à la fin de la spirale.
