    • An aircraft emergency oxygen dispensing device includes an oxygen storage vessel having a frangible pressure seal, and a manifold, a pressure regulator, one or more flow control valves connected to the oxygen storage vessel. The manifold includes an initiator for breaking the pressure seal to initiate a flow of oxygen. A flow controller controls the flow control valves to dispense small quantities of oxygen by a pulse oxygen system or a modulated oxygen system based on ambient cabin air pressure. In the pulse oxygen system, the flow controller further controls the flow control valves based on input from at least one breathing mask air pressure sensor that monitors the breathing of a user.
    • 飞行器应急氧气分配装置(19)包括具有易碎压力密封件(14)和歧管(16),压力调节器(18),一个或多个流量控制阀(20)的储氧容器(12) 到氧气储存容器(12)。 歧管(16)包括用于破坏压力密封件(14)以启动氧气流的引发器(26)。 流量控制器(22)控制流量控制阀(20)以基于环境舱内空气压力通过脉冲氧气系统或调节氧气系统分配少量氧气。 在脉冲式氧气系统中,流量控制器(22)基于来自监测用户呼吸的至少一个呼吸面罩气压传感器(46)的输入进一步控制流量控制阀(20)。
