Abstract

Abstract Translated from French O Le dispositif comprend une capsule-clapet (1) dont le plateau (4) porte un picot de fermeture (5) maintenu par des lames (6) au milieu d'un passage de sortie, ledit plateau (4) se développant en une jupe d'habillage (4a) de la bague (22) et comportant sur sa péri-phérie deux crans opposés (2, 3). La capsule-clapet (1) est associée à une enveloppe (9) qui présente un orifice central (11) et se développe en une jupe extérieure avec deux rampes internes (16, 21) servant d'appui aux crans latéraux (2, 3) de la capsule-clapet (1) pour son déplacement. O The device comprises a valve cap (1) whose plate (4) carries a closing pin (5) held by blades (6) in the middle of an outlet passage, said plate (4) developing in a covering skirt (4a) of the ring (22) and comprising on its periphery two opposite notches (2, 3). The valve cap (1) is associated with an envelope (9) which has a central orifice (11) and develops into an outer skirt with two internal ramps (16, 21) serving to support the lateral notches (2, 3 ) of the valve cap (1) for its movement.
