Abstract

L’invention concerne un ensemble disque de rupture, comportant un disque support soumis à la pression interne d’un réservoir de fluide ; un disque supérieur soumis à la pression extérieure au réservoir de fluide ; un joint d’étanchéité placé entre le disque support et le disque supérieur pour empêcher les fuites de fluide ; une pale nervurée dans laquelle sont formées une pluralité de pales de séparation par des lignes de découpe et subissant une déformation plastique du fait de la pression du fluide pour maintenir ainsi un passage d’écoulement ; et un disque d’ajustement qui éclate lorsque la pression dans le réservoir de fluide excède une pression prédéterminée. L’éclatement de l’ensemble disque de rupture suite à une pression excessive dans le réservoir de fluide crée un passage d’écoulement permettant l’échappement du fluide de façon à minimiser le risque d’endommagement du réservoir de fluide.
