Abstract

L'invention concerne des dispositifs pour des conduites hydrauliques. Le résultat technique consiste en un plus grand éventail de clapets anti-retour pour conduite permettant de réaliser des fonctions techniques supplémentaires sans accroître la longueur de montage de la conduite. Le clapet comprend une première pièce et une seconde pièce couplées rigidement et hermétiquement, un élément de fermeture avec un battant et une tige axiale possédant des sections protubérantes, un élément d'étanchéité annulaire élastique fixé rigidement sur un des côtés du battant central, et un ressort de compression. La première partie comporte deux conduites latérales communiquant par des cavités et via des ouvertures avec un canal traversant longitudinal de la première pièce. La seconde pièce du corps, du côté du canal traversant longitudinal opposé à la disposition de la seconde section de l'alésage, comporte une protubérance de réception d'extrémité afin d'assurer le couplage avec l'élément d'étanchéité annulaire élastique, ainsi qu'une gorge annulaire sur la surface latérale externe et des ouvertures radiales connectant la cavité de la gorge annulaire et le canal traversant longitudinal de la seconde pièce du corps. La gorge annulaire est disposée en face de l'ouverture sortant de la cavité de la seconde conduite latérale.
