Abstract

Robinet à clapet antiretour. Dans un robinet à boisseau tournant, et particulièrement à boisseau sphérique, le boisseau 7 comporte un alésage de retour 12 qui intersecte perpendiculairement celui d'écoulement normal 11. L'alésage 12 renferme une bille 14 coopérant avec un siège 13 et à course limitée par un manchon fendu 15. Il peut être prévu un ressort de rappel de la bille 14 et diverses combinaisons d'alésages et tubulures ou ouvertures sont possibles. Application comme vanne limitatrice de course d'un objet déplacé par un vérin hydraulique.
