(54) Title (EN): CHECK VALVE WITH INTEGRATED FILTER
(54) Title (FR): CLAPET ANTIRETOUR À FILTRE INTÉGRÉ

(57) Abstract:
(EN): A check valve may include an upper housing defining an inlet, a lower housing defining an outlet, and a cavity interposed between and defined by the upper and lower housings for fluidly connecting the inlet and the outlet. The check valve may further include a flexible valve member mounted in the cavity to selectively permit fluid flow in a first direction, and prevent fluid backflow in a second direction opposite to the first direction. A filter member may be mounted in the upper housing, upstream of the flexible valve member. The filter member may have an elongated portion configured to maximize surface area thereof exposed to the fluid flow, and restrict passage of undesirable matter in fluid flowing through the check valve.
(FR): L'invention concerne un clapet antiretour pouvant comprendre un boîtier supérieur définissant une entrée, un boîtier inférieur définissant une sortie et une cavité interposée entre les boîtiers supérieur et inférieur et définie par ceux-ci pour relier fluidiquement l'entrée et la sortie. Le clapet antiretour peut en outre comprendre un élément soupape flexible monté dans la cavité pour permettre sélectivement un écoulement de fluide dans un premier sens et pour empêcher un reflux de fluide dans un second sens opposé au premier sens. Un élément filtre peut être monté dans le boîtier supérieur, en amont de l'élément soupape flexible. L'élément filtre peut comporter une partie allongée, conçue pour maximiser la surface de celui-ci exposée au flux de fluide et pour limiter le passage de matière indésirable dans un fluide s'écoulant à travers le clapet antiretour.
