Claims (2)

1. Dispositif de décharge de pression adapté pour être monté sur une cuve ayant une ouverture dans une paroi terminale et comportant un rebord annulaire entourant cette ouverture, un joint en matière élastique étant monté dans un évidement périphérique de la circonférence extérieure du rebord annulaire, et un élément de fermeture de soupape, en forme de coupe, adapté pour reposer de façon étanche par sa partie discoidale sur la face terminale plane de ce rebord annulaire, un joint d'étanchéité étant monté entre ces parties dans la position de fermeture de l'élément de fermeture, un rebord périphérique de cet élément de fermeture entourant ce rebord annulaire et coopérant de façon étanche avec le joint monté dans la circonférence extérieure de ce rebord annulaire, ce joint étant disposé pour coopérer en frottement avec une surface intérieure du rebord, l'élément de fermeture de soupape étant rappelé en position de fermeture par des moyens de ressort, caractérisé en ce que le joint monté dans la ciconférence extérieure de rebord annulaire a une section transversale plate, l'évidement périphérique et le rebord étant disposés de telle sorte que le joint soit incurvé lorsque l'élément de fermeture de soupape est fermé de telle manière que la flexion du joint s'étend pratiquement sur toute sa largeur radiale, et que le joint reste plan lorsque l'élément de fermeture de soupape est dans sa position ouverte.
2. Dispositif de décharge de pression selon la revendication 1, caractérisé en ce que largeur de la région intérieure de l'évidement périphérique pour recevoir le joint dans la circonférence extérieure du rebord annulaire est pratiquement égale à l'épaisseur du joint et que la largeur de la région extérieure de cet évidement est supérieure à l'épaisseur du joint.
