Verfahren und Vorrichtung um das in einem versenkten Raum enthaltene Gas auf dem gleichen Druck zu halten wie draussen.

摘要

This invention relates to a device for maintaining the gas contained in a submerged enclosure in pressure equilibrium with the outside, comprising a plurality of deformable bags which are immersed at the same time as said enclosure which are filled with gas compressed to different pressures and which communicate with said enclosure via a manifold on which they are connected by automatic three-way valves.
