Title
(EN) VALVE CLOSURE WITH CONCENTRIC SPRING-LOADED MOVING VALVE MEMBERS, THE INTERNAL VALVE MEMBER HAVING AXIAL PROTRUSIONS
(FR) FERMETURE DE VANNE AVEC ÉLÉMENTS DE VANNE MOBILES À RESSORT CONCENTRIQUE, L'ÉLÉMENT DE VANNE INTERNE AYANT DES SAILLIES AXIALES
Abstract
(EN)
A valve closure for dispensing liquid by means of a pressurised gas has an inner sleeve (12) which includes a socket (16) and an annular inner valve seat (18). The inner sleeve carries a ring seal (14) which is urged against an outer valve seat (9) by an outer spring (15). A valve member (21) has an annular sealing face (23) co-operable with the inner valve seat (18) and a spring (24) urges the valve member (21) against the inner valve seat (18). The valve member (21) incorporates a plurality of projections (26) spaced radially inwards from the annular sealing face (23). The valve closure can be used with a dispensing coupler having a tubular probe with a circumferential ring seal and a locking recess to engage the locking fingers of a detachable closing element.
(FR)
Une fermeture de vanne destinée à distribuer un liquide au moyen d'un gaz sous pression comporte un manchon interne (12) qui comprend une douille (16) et un siège de vanne interne annulaire (18). Le manchon interne porte un joint annulaire (14) qui est poussé contre un siège de vanne externe (9) par un ressort externe (15). Un élément de vanne (21) a une face d'étanchéité annulaire (23) qui fonctionne conjointement avec le siège de vanne interne (18) et un ressort (24) pousse l'élément de vanne (21) contre le siège de vanne interne (18). L'élément de vanne (21) comprend une pluralité de saillies (26) espacées radialement vers l'intérieur à partir de la face d'étanchéité annulaire (23). La fermeture de vanne peut être utilisée avec un coupleur de distribution possédant une sonde tubulaire avec un joint annulaire circonférentiel et un évidement de blocage pour venir en prise avec les doigts de blocage d'un élément de fermeture séparable.
