Abstract

In a demand regulating device for use in airplanes traveling a wide range of altitudes a box having an inlet destined to be connected with an oxygen source and an outlet a mixing chamber inside said box means injectors communicating with said chamber and said outlet a demand valve for controlling the flow of oxygen through said injector means whereby a suction is developed within said chamber means to admit air from the ambient atmosphere to said operated box by a suction applied to said outlet means aneroid that respond to changes in altitude to control the amount of air passing to said box during the operation of said intake means and to interrupt said air flow at a predetermined altitude a flexible diaphragm mounted within said box and which responds to a suction applied to said outlet when said aneroid means have interrupted said air flow for op said valve with which oxygen flows through said means means injectors operated by the suction developed in said chamber to admit air from the ambient atmosphere to said mixing chamber whereby in said outlet a mixture of oxygen and air is created and second aneroid means responsive to altitude changes to variably control the amount of air passing to said chamber during operation of said aforementioned intake means or to interrupt said air flow at a predetermined second altitude.
