<p>A flexible package (7) for rescue equipment and specially adapted to be mounted on the exterior of a craft of submarine type, the package being compressible round its contents so that it will take up a minimum volume. The method of compressing the package is performed in a pressure vessel (1) containing fluid (5) in which the package is immersed. The package has a connection with a nonreturn valve (9) which is connected to a tube (8) communicating with the surrounding atmosphere. Pressurizing of the package takes place through a three way valve (4), when the air contained in the package is pressed out through the conduit. On evacuation of the pressure vessel the nonreturn valve will close and the compressed volume of the package will remain.</p> |
