A flexible package (7) for rescue equipment, specially adapted to be mounted on the exterior of a craft of the submarine type, the package being compressible around 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) into which the package is immersed. The package has a connection through a non-return valve (9) 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 expelled through the tube (8). On evacuation of the pressure vessel (1) the non-return valve (9) will close and the package (7) and its contents will remain in a compressed state. |
