The object of this study was to build and test a breadboard of an automatic oxygen regulator using fluidic techniques. Goals set for the regulator were that it should have oxygen economy, be rugged, simple, and self-powered. Feasibility of controlling the oxygen enrichment following a specified cabin pressure schedule was demonstrated. Features of the mixture control circuit were a fluidic function generator, a fluidic pulse duration modulator and an ejector pump. Feasibility of controlling the output pressure for normal breathing and pressure breathing as a function of cabin pressure was demonstrated. Major components in the closed pressure control loop were a fluidic function generator, a fluidic comparator amplifier, and a fluidically driven mechanical shutoff valve.
