Abstract:
(EN) A valve assembly includes two mutually opposed valves (10). Each valve (10) comprises a casing (12) in which a through passage (14) is defined. The passages (14) have at contiguous ends internally circumferential valve seats (16) against which respective movable valve elements (18) are biased. The elements (18) are capable of opening each other when held together. A coupling member (42) is provided to hold the valves (10) together. The casing (12) of one of the valves (10) has an extension (44) accommodating a flow regulating control valve (30, 64) at its distal end. The extension (44) has a branch (46) to be connected to a reservoir.
(FR) Un ensemble de vannes comprend deux vannes (10) opposées mutuellement. Chaque vanne (10) comprend un corps (12) déterminant un passage traversant (14). Les passages (14) possèdent à leurs extrémités contiguës des sièges de vanne (16) circulaires intérieurement contre lesquels les éléments de vanne mobiles respectifs sont sollicités. Les éléments (18) peuvent s'ouvrir quand ils sont maintenus en contact. Un élément d'accouplement (42) est prévu pour maintenir les vannes (10) en contact. Le corps (12) de l'une des vannes (10) possède un prolongement (44) abritant à son extrémité distale une vanne de commande de régulation de débit (30, 64). Le prolongement (44) possède un branchement (46) de liaison à un réservoir.
