The aircraft emergency oxygen supply system (10) includes one or more sources of supplemental breathable oxy-gen (12a, 12c), one or more inlet valves (16a, 16c) for one or more breathing devices (18a, 18c), connected to the inlet valves, and one or more cabin air pressure transducers (24). A pressure contoller (20) controls the inlet valves in response to the one or more cabin air pressure transducers. One ore more second pressure transducers may connected to conduits downstream of inlet valves to be monitored, and the presure controller may also control operation of the inlet valves in response to the one or more second pressure transducers.
Linvention concerne un système dalimentation en oxygène durgence pour avion (10) comportant une ou plusieurs sources doxygène respirable dappoint (12a, 12c), une ou plusieurs soupapes dadmission (16a, 16c) pour un ou plusieurs dispositifs de respiration (18a, 18c), raccordés aux soupapes dadmission, et un ou plusieurs capteurs de pression dair cabine (24). Un régulateur de pression (20) commande les soupapes dadmission en réponse au ou aux capteurs de pression dair cabine. Un ou plusieurs seconds capteurs de pression peuvent être raccordés à des conduites en aval des soupapes dadmission à surveiller, et le régulateur de pression peut également commander le fonctionnement des soupapes dadmission en réponse au ou aux seconds capteurs de pression.
