Valve apparatus 10 for use in fluids storage vessels comprises an inlet 60 for receiving a pressurised fluid to be stored in such a storage vessel, an outlet 94 for discharging pressurised fluid into the vessel, a flow valve arrangement for controlling flow of the pressurised fluid between the inlet and outlet, and an outlet valve 12 moveable from a flow preventing position to a flow permitting position to permit discharge of fluid stored in the vessel via an opening in the vessel. The valve apparatus is adapted such that, in use, discharge of the pressurised fluid from the outlet 94 to refill the vessel is prevented until the outlet valve 12 has at least substantially returned to its flow preventing position.

Vanne (10) de réservoir de stockage, comprenant : une entrée (60) pour fluide comprimé destiné à être stocké dans le réservoir; une sortie (94) permettant d'évacuer le fluide comprimé dans le récipient; une vanne de réglage, qui commande l'écoulement du fluide entre l'entrée et la sortie; et une soupape de refoulement (12) pouvant passer d'une position fermée, qui empêche l'écoulement, à une position ouverte, qui permet au fluide stocké dans le réservoir de s'écouler par une ouverture pratiquée dans ce dernier. La vanne est conçue de sorte que le fluide ne puisse pas être refoulé par la sortie (94) et remplir le réservoir tant que la soupape de refoulement (12) n'est pas, au moins substantiellement, retournée à sa position fermée.
