Abstract: An aircraft lavatory oxygen source includes an oxygen storage vessel having a manifold, and an actuator configured to break a pressure seal of the oxygen storage vessel to initiate a flow of oxygen. A flow path in the manifold includes one or more oxygen flow rate control orifices, and may include a variable orifice to control oxygen flow rate and pressure through an outlet of the manifold. The outlet includes a swivel connector fitting that rotates 360 degrees, and one or more oxygen distribution tubes connected with one or more removably attachable connectors, directly to the outlet, between portions of the tube, or to a breathing mask. The actuator can include a spring loaded mechanism, a pyrotechnic mechanism, an electrically powered solenoid or a pneumatic pressure initiated device.

Abstract: Various adaptor configurations are provided that allow newly mandated replacement oxygen modules to replace oxygen generators in the same containers that are currently used in aircraft lavatories. The replacement modules and oxygen generators differ in terms of overall interface dimension, geometries and weights. The adaptors enable replacement modules to be mounted without, or with only minimal, modification of the oxygen containers.
