Abstract

Cet ensemble comprend un premier et un second distributeurs 14, 15 présentant chacun un premier 17, un deuxième 18, et un troisième 19 orifice et un élément de commande 20, 25 respectif de l'écoulement du fluide, déplaçable de façon à augmenter l'écoulement dans un premier parcours qui contient le premier et le deuxième orifice et à diminuer simultanément l'écoulement dans un second parcours, qui contient le premier et le troisième orifice et vice versa, les éléments de commande étant couplés l'un à l'autre par des ressorts 29, 30 de façon à se déplacer conjointement dans des conditions normales et réagissant à des pressions intermédiaires dans des parcours précités à travers les distributeurs. Une différence dans les débits respectifs du fluide à travers les distributeurs, que le fluide provienne d'une source commune 32 ou qu'il retourne, a pour effet'de déplacer les éléments de commande 20, 25 dans le sens qui provoque une diminution de cette différence.
