Air venting device in a container subjected to uncontrolled oscillations

Gas venting device in a container with a sealed closure, wherein the container is a torpedo tube of a submarine or a missile launcher of a ship, subjected to uncontrolled oscillations and designed to be filled by a liquid comprising a filling orifice for introducing the liquid to the container, said device consisting of a tube of which one part is inside and one part outside the container and connected to one another, the inside part being normally open to allow the gas pushed back by the liquid filling the container to enter the tube, and the outside part comprising a liquid present indicator to detect the ingress of liquid and thus indicate that the container has been filled by the liquid, and an isolating valve to close off said outside part of the tube in response to the liquid presence indicator;

• said device being characterized in that the part of said tube inside the container comprises at least two open ends located at different parts in the container, at least one of the ends being fitted with a closure flap to close off said end once the liquid reaches a predetermined level below the level necessary for it to enter said tube, in such a way that said end allows gas to enter even when the container is subjected to uncontrolled oscillations and so long as the container is not completely filled by the liquid, such that the liquid presence indicator can never detect the presence of liquid until the container is completely filled.
