Abstract
A gas flow controller 10 for use with a molecular sieve type oxygen enrichment of air system 5 delivering oxygen enriched air for breathing by aircrew ensures that a constant preset quantity of product gas in the form of oxygen enriched air flows from the system 5 so that it performs under varying demand conditions and varying air supply conditions to maintain desired levels of oxygen concentration in the oxygen enriched air delivered to the aircrew by means of a demand regulator 6 and a breathing mask 7. A servo-operated valve means 20 bleeds air from downstream of a venturi section 15 provided between in the inlet 13 and outlet 14 of a gas flow duct 12 in the body 11 of the controller 10. The servo-operated valve means 20 is regulated by an actuator means 29 responsive to pressure difference through the venturi section 15. An adjustment means 42 responsive to duct pressure upstream of the venturi section and either to varying cabin absolute pressure or to varying cabin differential pressure, applies a biasing force to the actuator means.
