Abstract

Appareil destiné à régler en fonction des variations de la pression ambiante les proportions de deux gaz à mélanger. Cet appareil comprend deux conduites d'alimentation, deux régulateurs de débit accouplés, de telle sorte que l'ouverture de l'un correspond à la fermeture de l'autre, deux régulateurs de pression situés en amont des deux précédents, et un moteur qui fait fonctionner ces derniers en fonction de la pression ambiante. Application notamment aux systèmes d'alimentation en air respirable des équipages d'aéronefs.
