Oxygen supply system and device therefor

摘要

A stand alone oxygen supply system associated with a mask assembly of the type including a face mask (28) and an inflatable head harness (26). The mask assembly is normally stored in a stowage box (10) which also includes a reservoir (20), a relatively large chemical oxygen generator in the form of a chlorate candle (18) and a plurality of relatively small oxygen supply devices in the form of small chlorate candles (38). The small candles are caused to be sequentially fired to maintain an oxygen supply under pressure within the reservoir (18) during storage and/or tests.
