Abstract

La présente porte sur un ensemble de siège de soupape à bille qui permet une décharge d'une pression de cavité. L'ensemble comprend un corps de soupape pour recevoir un siège annulaire souple. Des premiers passages dans le siège fournissent une communication entre la cavité de la soupape et un espace formé entre le siège et le corps de la soupape. Si la pression de la cavité atteint un niveau précis, un point de scellage entre le siège et le corps de la soupape est perdu. Par conséquent, une communication est fournie entre l'espace et le passage de la soupape pour atteindre une décharge de la pression de la cavité.
