Abstract

Appareil respiratoire. Il comporte une vanne d'admission 20, manoeuvrée par un diaphragme 12, ce diaphragme coopérant à la manière d'une vanne avec une surface d'étanchéité 24, contre laquelle il est normalement appliqué et dont il s'écarte lors de l'expiration pour ouvrir une sortie 22. Cette structure évite d'avoir à prévoir une vanne de sortie indépendante. Application aux appareils respiratoires dont la soupape d'admission est commandée par inspiration du gaz.
