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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to provisional application 61 / 724,772, filed November 9, 2012, and non-provisional application 14 / 073,590, filed November 6, 2013, which are incorporated by reference merged here. technical field [0003] The present invention generally relates to emergency oxygen supply systems such as are commonly carried on commercial aircraft for effective use following a loss of cabin pressure. More specifically, the present invention relates to a source of oxygen for aircraft lavatories for use in depressurized conditions to prevent an effect known as hypoxia. Background technique [0004] To supply oxygen to passengers following a loss of cabin pressure at altitudes greater than 10,000 feet, emergency oxygen supply systems are often installed on board aircraft. Such systems typically include a mask adapted to fit over the mouth and nose, which is released from an overhead storage compartment wh...
