Abstract
L'invention concerne un système de traitement d'eau doté d'une unité d'osmose (14) inverse, comprenant un réservoir de stockage (40) dont le logement de réservoir (42) extérieur renferme une vessie expansible (50). Une région sous pression (62) est définie entre l'extérieur de la vessie (50) et l'intérieur du logement (42). Un ensemble vanne de commande (44) commande la distribution d'eau de source sous pression vers une région de mise sous pression (62) et la communication de ladite région (62) avec un drain (22). L'ensemble (44) comprend une vanne pilote (70) sensible à un état de distribution, et un élément de vanne (76) qui se déplace entre une première position de distribution et une seconde position de non distribution. Une électrovanne (72) est sensible à la position de la vanne pilote (70) et distribue l'eau de source sous pression à la région (62) lorsque ladite vanne pilote (70) se trouve dans la première position, ce qui exerce une pression sur la vessie (50) permettant d'expulser l'eau traitée, et relie la région (62) et le drain (22) lorsqu'il n'y a pas de distribution de sorte que la vessie (50) peut se déployer lorsqu'elle reçoit l'eau traitée de l'unité d'osmose (14) inverse.
