ABSTRACT:
An on-board oxygen generating system (OBOGS) includes a molecular sieve oxygen generating system (MSOGS), a breathable gas delivery regulator selectively operable to deliver 100 percent MSOGS output gas or air diluted output gas to a user, a back-up storage plenum and control means arranged so that when air diluted delivery gas is selected a portion of 100 percent MSOG output gas is diverted to charge the storage plenum and when 100 percent MSOG output delivery gas is selected diversion to the storage plenum is automatically prevented. The breathable gas delivery regulator includes an injector adapted to induce a flow of air to mix with 100 percent MSOG output gas when air diluted delivery gas is selected.
