Abstract

Dans une vanne à double siège du type à cage, ne demandant qu'une faible énergie pour son actionnement, l'invention a pour but de limiter la sensibilité de la vanne aux écarts de pression qui peuvent se présenter dans le parcours d'écoulement. A cet effet un dispositif élastique, intervenant entre un clapet principal creux 7 et un clapet intérieur 32 de faible portée, se compose de deux éléments à caractéristiques différentes tels qu'un ressort 44 à caractéristique linéaire et une rondelle élastique 47 à variation brusque du sens et de la valeur de la force exercée.
