Abstract
Soupape d'inhalation fonctionnant à la demande et destinée à commander l'alimentation d'un masque facial en gaz sous pression. Elle comprend un diaphragme sensible à la différence entre la pression ambiante et la pression d'inhalation exercée par une personne portant le masque, et un dispositif indépendant du diaphragme et qui, sous l'effet de l'écoulement du gaz dans la soupape, produit une aspiration augmentant l'ouverture de l'obturateur de la soupape afin de réduire l'effort demandé à la personne pour respirer. Domaine d'application : masques respiratoires.
