Title (EN) LOW SPILL FEMALE COUPLING
(FR) COUPLEUR FEMELLE A FAIBLES PERTES
Abstract:
(EN) A female coupling member (20) includes a body (31) portion, a slidable sleeve (52) positioned in the body portion and an axially extending stem valve (64) sealingly engageable with the sleeve (52). Axial movement of the sleeve (52) relative to the stem valve (64) opens the female coupling member (20) to the flow of fluid. The stem valve (64) is provided with a cavity sized to receive a protruding nose of a male member (10) to be attached thereto. The slidable sleeve (52) and the stem (64) valve are designed to receive the male coupling member (10) including its flat insertion end (12) and protruding nose (27) with minimal air inclusion and minimal fluid loss upon disengagement.
(FR) L'invention porte sur un coupleur femelle rapide (20) comportant un corps (31), un manchon coulissant (52) placé dans le corps et une soupape à tige (64) venant obturer le manchon (52). Lorsque le manchon se déplace axialement par rapport à la soupape à tige (64), le coupleur femelle (20) s'ouvre pour livrer passage au fluide. La soupape à tige (64) comporte une cavité dimensionnée pour recevoir l'embout saillant d'un élément mâle (10) pouvant s'y fixer. Le manchon coulissant (52) ainsi que la soupape à tige (64) sont conçus pour recevoir l'élément mâle (10) y compris son extrémité plate d'insertion (12) et son embout saillant (27) avec un minimum d'inclusions d'air et un minimum de pertes de fluide lors du désaccouplage.
