摘要

Improvements in expiratory apparatuses characterized by the arrangement of a regulating gas passage mounted on the face of a mask having a breathing chamber connected to the atmosphere by means of a regulating valve of the aspiration comprising a regulator of the intake section that includes an intake diaphragm that operates in relation to the pressure of the mask to control the opening and closing of the intake valve devices to supply the breathing chamber with respiration gas and characterized by a separable removable regulator of the pressure of the chamber of respiration mounted on the rear surface of the regulator and including devices sensitive to atmospheric pressure to expand in height and exert a deflection force on said diaphragm at a certain altitude.
