Abstract

Un régulateur de pression et de débit d'un gaz respiratoire, à la demande et à dilution, comporte une admission (8) en gaz additionnel et une sortie (4) vers un masque respiratoire ainsi que des moyens de dilution (5).
Des moyens de commande (23) commutent une alimentation (27) en gaz additionnel sous pression entre au moins deux passages (25, 26). Au moins un de ces passages correspond à un débit économique et a une section restreinte pour limiter le débit de gaz additionnel transmis à l'admission (6). L'autre passage (26) a une section telle que le gaz additionnel ait un débit maximum pour alimenter l'utilisateur en gaz additionnel de manière physiologiquement suffisante.
