Abstract

Le régulateur à la demande comprend des moyens de mise en communication d'un e admission (12) de gaz respiratoire sous pression avec une tubulure (14) destinée à être reliée à l'intérieur d'un masque respiratoire, des moyens (3 4, 32) d'apport d'air de dilution au gaz respiratoire, et un clapet d'expiratio n (36) s'ouvrant de la tubulure vers l'atmosphère. De plus, un organe de commande manuelle (38) a une position normale provoquant le fonctionnement sans surpression et avec dilution et une position de secours provoquant l'alimentation de la tubulure en gaz respiratoire pur et en surpression. Des moyens mécaniques ou pneumatiques interdisent le fonctionnement avec l'alimentation en gaz en surpression aussi longtemps que le masque est stock é.
