The manifold includes a lock for immobilizing the plenum body with respect to the locating plate in at least a first position. In another aspect, a COG is provided. The COG may have a housing and a locking manifold.

A system for delivering breathing gas to passengers on-board an aircraft, including: a source of breathing gas, at least one face mask for passengers, a reservoir associated with each face mask, a delivery valve for each face mask, the delivery valve being disposed between the source of breathing gas and the reservoir, the reservoir being disposed between the delivery valve and the face mask, a sensor associated with each reservoir and configured to sense a filling of the reservoir, and a controller configured to control the delivery valve in a continuous supply mode to provide a continuous flow of breathing gas to the reservoir and to interrupt the continuous flow of breathing gas when the filing sensed by the sensor is a filling threshold.

An aircraft emergency oxygen supply system includes: at least one passenger oxygen mask; a compartment for housing the at least one passenger oxygen mask; and at least one oxygen hose. E each of the at least one passenger oxygen mask is coupled to a respective oxygen hose for supplying a gas comprising oxygen to the respective oxygen mask; at least one fixing clip. Each of the at least one fixing clip comprises a lanyard fixing portion and at least one C-shaped oxygen hose fixing portion for releasably holding one or more oxygen hoses. For each of the at least one fixing clip, the aircraft emergency oxygen supply system comprises a lanyard having a first end, which is fixed at the compartment, and an opposing second end, which is fixed to the lanyard fixing portion of the respective fixing clip.

An apparatus for preparing a ventilation gas mixture to a user comprises: a gas mixing device configured to receive oxygen through a first gas feed, the gas mixing device being further configured to received exhaled air from a person; a gas reservoir configured to receive the exhaled air from the gas mixing device through a second gas feed, wherein the gas reservoir is further configured to re-supply the exhaled air to the gas mixing device through the second gas feed; an altitude sensor configured to determine altitude information; a control system configured to receive the altitude information from the altitude sensor and further configured to control the flow of oxygen through the first gas feed based on the received altitude information; wherein the gas mixing device is arranged to combine the oxygen received through the first gas feed with the re-supplied exhaled air received through the second gas feed in order to prepare a ventilation gas mixture.

An aircraft emergency oxygen supply device comprises an oxygen source for supplying oxygen gas; a backup electric power supply system, comprising at least one electric power storage device; and a controller for controlling the operation of the aircraft emergency oxygen supply device. The aircraft emergency oxygen supply device is electrically connectable to an aircraft electric power supply system for being supplied with electric power provided by the aircraft electric power supply system; the at least one electric power storage device is chargeable by electric power provided by the aircraft electric power supply system; and the aircraft emergency oxygen supply device is operational with electric power provided by the backup electric power supply system.

An emergency oxygen system for aircraft comprising: a breathing gas supply circuit to be connected upstream to a source of breathing gas and downstream to at least one mask, a flow control valve configured to adjust the flow of breathing gas supplied to the mask, an electronics board configured to control the flow control valve, a power source, a switching device interposed between the power source and the electronics board, the switching device comprising a switch configured to have a first state in which power from the power source is supplied to the electronics board and a second state in which the electronics board is not supplied with power from the power source.

Described herein are a system for providing oxygen to oxygen masks in an aircraft, and an associated method for regulating the oxygen flow in an efficient manner. The system has an oxygen tank, oxygen masks, first and second oxygen lines, and an electrically controllable valve. The valve is coupled to the oxygen tank and the two oxygen lines. The oxygen masks are coupled to the oxygen lines downstream of the valve to accommodate the transfer of oxygen from the oxygen tank via the valve. In a working state when an electrical signal is applied the valve produces a connection between the oxygen tank and the first oxygen line when required, and permanently prevents a connection between the oxygen tank and the second oxygen line. When in a rest state, the valve produces a permanent connection between the oxygen tank and the second oxygen line.
