Title (EN) IMPROVED VALVE ASSEMBLY
(FR) ENSEMBLE DE SOUPAPE AMÉLIORÉ
Abstract:
(EN) A valve assembly for use with a container for holding a fluid comprising a liquid and a gas, the valve assembly comprises a housing having an internal chamber therein and an inlet and an outlet to and from the internal chamber, the internal chamber in use being in fluid communication with the container and providing for an exhaust route for fluid from the container to the outlet. The valve assembly further includes a check valve including a sealing member movable between a check valve open position, and a check valve closed position, the sealing member having one or more through holes therein, the check valve when in the check valve open position providing for a main flow route for fluid leaving the internal chamber via the outlet, the through hole(s) in the sealing member providing for a limited return flow route for gas returning to the internal chamber via the outlet when the check valve is in the check valve closed position. The valve assembly further comprises a breather check valve movable between a breather valve open position in which it provides fluid communication between the exhaust route and externally of the housing, and a breather valve closed position, and a filter which is in gas communication with the breather check valve for filtering gas before the gas enters the internal chamber and container.
(FR) La présente invention concerne un ensemble de soupape pour utilisation avec un récipient destiné à contenir un liquide comprenant un liquide et un gaz, l'ensemble de soupape comportant un boîtier comprenant une chambre interne dans son volume intérieur et un orifice d'entrée vers la chambre interne et un orifice de sortie depuis celle-ci, la chambre interne lors de l'utilisation étant en communication fluidique avec le récipient et fournissant un trajet de décharge pour le fluide depuis le récipient vers l'orifice de sortie. L'ensemble de soupape comporte également un clapet anti-retour comprenant un élément d'étanchéité mobile entre une position ouverte du clapet anti-retour, et une position fermée du clapet anti-retour, l'élément d'étanchéité comprenant un ou plusieurs trou(s) traversant(s) à l'intérieur, le clapet anti-retour lorsqu'il se trouve dans la position ouverte de clapet anti-retour fournissant un chemin d'écoulement principal pour le fluide sortant de la chambre interne par l'orifice de sortie, le (s) trou(s) traversant (s) dans l'élément d'étanchéité fournissant un trajet d'écoulement de retour limité pour le gaz revenant vers la chambre interne à travers l'orifice de sortie lorsque le clapet anti-retour est dans la position fermée de clapet de anti-retour. L'ensemble de soupape comporte en outre un clapet anti-retour de reniflard mobile entre une position ouverte dans laquelle il fournit une communication fluidique entre le trajet de décharge et l'extérieur du boîtier, et une position fermée de soupape de reniflard, et un filtre qui est en communication gazeuse avec le soupape anti-retour de reniflard pour filtrer le gaz avant la pénétration du gaz dans la chambre interne et le récipient.
