Abstract

Nouvelle vanne utilisée pour la ventilation du fond d'une coupelle d'alimentation en fluide, ladite vanne comprenant une base (2) pouvant être mise en correspondance avec un boîtier de vanne (1) au fond de la coupelle d'alimentation en fluide, un élément de blocage (3) étant articulé sur la base (2). Une broche de tenon (5) utilisée pour sceller un trou d'évent (4) au fond de la coupelle d'alimentation en fluide est disposée sur l'élément de blocage (3), une boucle de verrouillage étant disposée sur la paroi externe de la base (2). La boucle de verrouillage est mise en correspondance avec la paroi interne du boîtier de vanne (1), au moins une bague de fixation étant disposée sur la paroi interne du boîtier de vanne (1). Au moyen de la correspondance entre une paroi interne (8) d'une position de verrouillage (7) et une paroi latérale (9) de l'élément de blocage (3), la position de verrouillage (7) se déforme lorsqu'elle vient juste en contact avec l'élément de blocage (3). Lorsque la totalité de l'élément de blocage (3) est serrée, la paroi interne (8) de la position de verrouillage (7) retrouve la forme d'origine, de telle sorte que l'élément de blocage (3) peut être serré dans la position de verrouillage (7) plus facilement, ce qui signifie que la base finie ne subit sensiblement aucune déformation, et la stabilité des performances du produit fini est considérablement améliorée.
