Title:
Emergency oxygen equipment for airplane bathrooms
Document Type and Number:
Japanese Patent JP6067847
Kind Code:
B2
Abstract:
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.
