ABSTRACT:
A gas actuated valve enabling high-speed actuation silently and rapidly os one or more blocked ports in a floodable container, thereby permitting the flooding of the otherwise closed container by ambient fluid. The valve includes a sleeve mounted for sliding movement about a base, the latter being attached to the interior of the container at each port. An electrically-initiated, gas-generating pyrotechnic bolt is threadedly connected between, and disposed in a cavity defined between the sleeve and the base. The bolt, before actuation, functions as a tensile member to withstand ambient pressure, thereby preventing the valve from opening prematurely. When actuated, the bolt fuses, separates, and releases hot gases into the cavity which expand and bear against the sleeve, causing the sleeve to move away from the port so that the container port opens completely thereby flooding the container.
