Abstract

A demand pressure reducing device for respiratory apparatus, which comprises a chamber limited by a flexible membrane subjected on its external face to the pressure of the environment, and connected on the one hand to an inspiration duct and on the other to an air source. pressure, which sends to the chamber through a valve controlled by the displacement of the membrane under the effect of the respiratory movements of the wearer of the apparatus, a jet of air in a direction that does not end at the entrance of the aspiration duct, characterized because an obstacle deflects the jet of air that enters the pressure reducing chamber towards the entrance of the inspiration duct.
