A self-sealing valve comprises a valve housing having a fluid conduit, a valve seat, and a retaining member, the valve housing being configured to pass fluid through the fluid conduit, and a flexible diaphragm comprising a flexible material having resiliency, wherein the retaining member and the flexible diaphragm are configured so that the retaining member retains a portion of the flexible diaphragm so as to use the resiliency of the flexible material to bias the flexible diaphragm against the valve seat to a closed position of the self-sealing valve to provide a self- seal of the fluid conduit, and to facilitate movement of the flexible diaphragm under a fluid bias against a first side of the flexible diaphragm in a first direction away from the valve seat to an open position, and wherein the retaining member and the flexible diaphragm are configured so that the self-sealing valve can be contacted to move a portion of the flexible diaphragm away from the valve seat to the open position.

La présente invention concerne une valve auto-obturante qui comprend un logement de valve comportant un conduit de fluide, un siège de valve et un élément de retenue. Ledit logement est conçu pour le passage d'un fluide dans ledit conduit, et un diaphragme souple comprend un matériau souple possédant une certaine résilience. L'élément de retenue et le diaphragme souple sont conçus de sorte que l'élément de retenue retienne une partie dudit diaphragme de façon à utiliser la résilience du matériau souple pour solliciter ledit diaphragme contre le siège de valve vers une position fermée de la valve auto-obturante afin d'assurer une auto-obturation du conduit de fluide, et pour faciliter le mouvement dudit diaphragme sous une sollicitation par le fluide contre un premier côté du diaphragme souple dans une première direction à l'écart du siège de valve vers une position ouverte. L'élément de retenue et le diaphragme souple sont conçus de sorte que la valve auto-obturante puisse être contactée pour déplacer une partie dudit diaphragme à l'écart du siège de valve vers la position ouverte.
