摘要:
Oxygen breathing masks, as well as methods of providing oxygen to persons, are detailed. The devices may include mechanisms for supplying either oxygen or ambient air to a person depending on inspiration pressure applied by the person to a first volume to which the person's mouth and/or nose is connected.

An emergency oxygen system is provided for aircraft passengers. The system includes at least one oxygen mask (2), with a sensor (4) for detecting at least one breathing characteristic value of a passenger using this oxygen mask (2). A control unit (10) individually determines the oxygen requirement of the passenger on account of the detected breathing characteristic value. A dosing device (8) is actuated by the control unit (10). The dosing device (8) supplies an oxygen quantity corresponding to the determined oxygen requirement, to the oxygen mask (2).

There is provided a regulation valve for a life support system for use in an aircraft cabin. The valve may have a gas inlet, an air mask supply outlet connected to the gas inlet, and a pressure vest branch interconnected between the gas inlet and an opening. The valve may further have a decompression valve adapted to inhibit gas flow from the pressure vest branch to the air mask supply outlet if pressure in the aircraft cabin decreases below a predetermined value, a one-way valve adapted to inhibit gas flow from the pressure vest branch to the air mask supply outlet at a predetermined pressure difference between the pressure vest branch and the gas inlet, and a one-way dump valve adapted to direct gas from the pressure vest branch to the environment at the predetermined pressure difference between the pressure vest branch and the gas inlet.

摘要:
An oxygen emergency supply device for an aircraft includes an oxygen pressure vessel, which is in fluid connection with at least one oxygen mask. Means for closing and opening the oxygen pressure vessel, means for pressure reduction, a pressure regulation device, and a flow throttle are provided in the conduit connection between the oxygen pressure vessel and the oxygen mask. The oxygen emergency supply device further includes a control device. A controllable shut-off valve forms the means for closing and opening the oxygen pressure vessel, the means for pressure reduction and a part of the pressure regulation device.

The invention relates to an oxygen breathing device for an aircraft, in particular for oxygen supply to crew member in a cockpit of an aircraft, comprising a filter unit having an inflow port and an outflow port, the filter unit being adapted to extract nitrogen from an air flow flowing from the inflow port to the outflow port through the filter unit, wherein the filter unit is adapted to receive compressed air, preferably, bleed air from a precompressor stage of a turbine driving the aircraft, or directly by a separate electrically driven compressor, via a bleed air supply line connected to the inflow port, a first pressure regulator in the bleed air supply line, a first water separator which is arranged in the bleed air supply line in flow direction of the bleed air before the first pressure regulator and a connection port which can be brought in fluid communication with said outflow port of the filter unit and which is adapted to be coupled to at least one oxygen supply mask via an oxygen supply line. According to the invention, a chemical oxygen generator comprising at least one substance adapted to produce oxygen in a chemical reaction and to provide said oxygen to an outflow port of said oxygen generator is provided. The outflow port of said chemical oxygen generator is connected to an auxiliary oxygen supply line and a control unit is adapted to selectively provide oxygen from the filter unit or the chemical oxygen generator to an oxygen supply mask coupled to the connection port.
