在航空器内使用的按需求调节的稀释氧气调节器
摘要：
本发明披露了一种系统和方法，为加压航空器客舱内的乘客自动提供合适流量的氧气。在一实施例中，在加压航空器客舱内使用的一种按需求调节的稀释氧气系统包括一氧气启动和需求调节系统，该系统被设置成根据加压航空器客舱内的乘客的肺容量在甲海拔高度范围内对气压落差作出反应，从而在甲海拔高度范围内控制流向一呼吸出口的压缩氧气。所述按需求调节的稀释氧气系统亦包括一客舱空气稀释和输送系统，该系统与所述氧气启动和需求调节系统连接，也被设置成在乙海拔高度范围内对气压落差作出反应，并且在乙海拔高度范围内向一呼吸仪器提供浓度逐渐提高的混合气体，直至提供百分之一百的净压缩氧气。
摘要（英）：

A system and method of automatic delivery of appropriate flow rate of oxygen to a person flying in a pressurized aircraft cabin is disclosed. In one embodiment, an adaptable demand dilution oxygen regulator for use inside a pressurized aircraft cabin, includes an oxygen initiation and demand regulation system adapted to be responsive to differential gas pressure in a first altitude range based on a pulmonary capacity of a person flying in the pressurized aircraft cabin and to control flow of pressurized oxygen to a breathing outlet during the first altitude range. The adaptable demand dilution oxygen regulator further includes a cabin air dilution and delivery system, coupled to the oxygen initiation and demand regulation system, adapted to be responsive to differential gas pressure in a second altitude range and to output progressively enriched mixture till 100% pressurized oxygen into a breathing apparatus during the second altitude range.
