A process and apparatus provides breathing gas for occupants of pressurized cabins, e.g., cabins in aircraft, by passing a compressed air through adsorbers for increasing the relative oxygen concentration thereof. The same apparatus is simultaneously employed for providing an emergency breathing gas supply stock. In normal operation, the supply from the adsorber is selectively switched to partially flow into an emergency storage tank for storing enriched oxygen breathing gas therein, and then switched back into supplying a total flow of the normal breath...
In a process for providing breathing gas for occupants of pressurized cabins in aircraft wherein said breathing gas is normally provided by passing air through adsorbers in aircraft for increasing the oxygen concentration of the air, the improvement comprising: withdrawing a portion of the oxygen-enriched breathing gas from said adsorbers and storing said portion of oxygen enriched breathing gas as an emergency supply of breathing gas for consumption only in the event of an interruption of the normal breathing gas supply.
