Abstract[English]
A valve assembly (130) for a fuel tank is disclosed, featuring a valve housing (132) with an inlet (133), outlet (144), and an internal chamber. A cage (171) is positioned within this chamber, housing a movable sealing element (168) with a disk (148) at its lower end. This disk includes apertures (210) for vapor passage. An outer seal (174) is coupled to the bottom of the cage. Below the disk is an over pressure release (OPR) seal (142), to which an inner seal component (443) with a seal lip 450 is attached. The inner seal component is configured to seal a vapor passage between the disk and the OPR seal when these components are pressed together. Conversely, the seal lip guides vapor flow toward this passage when the disk and OPR seal separate.[French]
L'invention concerne un ensemble soupape (130) pour un réservoir de carburant, comprenant un boîtier de soupape (132) avec une entrée (133), une sortie (144) et une chambre interne. Une cage (171) est positionnée à l'intérieur de cette chambre, logeant un élément d'étanchéité mobile (168) avec un disque (148) à son extrémité inférieure. Ce disque comporte des orifices (210) de passage de vapeur. Un joint externe (174) est couplé au fond de la cage. En dessous du disque se trouve un joint de libération de surpression (OPR) (142), auquel est fixé un composant d'étanchéité interne (443) pourvu d'une lèvre d'étanchéité (450). Le composant d'étanchéité interne est conçu pour obturer un passage de vapeur entre le disque et le joint OPR lorsque ces composants sont pressés l'un contre l'autre. Inversement, la lèvre d'étanchéité guide le flux de vapeur vers ce passage lorsque le disque et le joint OPR se séparent.
