(1) the purpose of the oxygen system is to provide oxygen for the flight crew and passengers when required. Two independent oxygen system are installed in B737. the flight crew oxygen system is a high pressure gaseous system for flight crew use only, this type of system is designated a “diluter demand” system . The passenger oxygen system is a chemically-generated oxygen system for use by passengers and cabin attendants. This type of system is designated a “continuous flow” system.

氧氣系統用來為機組及旅客提供氧氣。 B737上安裝有兩套氧氣系統。機組氧氣系統是一個僅供機組使用的高壓氣態系統，這種系統被稱為“稀釋要求”系統。旅客氧氣系統是一供旅客及乘務員使用個化學制氧系統。這種系統被稱為“ continuous flow”系統。

(2) The flight crew oxygen system consists of an oxygen cylinder. Valves, indicating components, distribution tubing and oxygen mask/regulator. The crew oxygen system components are located in the forward cargo compartment and in the flight compartment.

機組氧氣系統包括一個氧氣瓶，閥門，指示組件，分配管道及氧氣面罩/調節器。機組氧氣系統組件安裝在前客艙和駕駛艙內。

(3) Oxygen flows through the pressure reducing regulator and shut off valve

to the masks. Quantity (pressure) indication is provided by a gage in the flight compartment. In the event of an overpressure, the cylinder is vented to ambient through the overboard discharge. The cylinder is serviced after removal from the aircraft.
氧氣通過減壓調節器和關斷活門流向氧氣面罩。流量指示由駕駛艙內的壓強計指示。一旦過壓，氣瓶將通過頂部釋放開關進行釋壓。氣瓶應從飛機上取下進行勤務。
(4) The passenger oxygen system provides an emergency oxygen supply to the passengers and attendants, this system consists of passenger sevice units, control and indication. This service units contain the mask box, door latch release actuator, latching mechanism, chemical oxygen generator and oxygen mask.
