The method serves for operating an air fractionization installation for obtaining oxygen on board an aircraft, with at least two molecular sieve chambers. A part mass flow of the oxygen obtained in the respective adsorbing molecular sieve chamber is supplied for flushing a desorbing molecular sieve chamber. The quantity of the flushing oxygen led to the desorbing molecular sieve chamber is controlled by way of this.

The present invention relates to an oxygen breathing device, in particular for providing oxygen to passengers or crew of an aircraft, the device comprising an oxygen source for providing pressurized oxygen, a valve connected to the oxygen source via a pressure line, a control unit for controlling said valve, and at least one nozzle for dispensing the oxygen passing through said valve. In particular, the present invention relates to an oxygen breathing device comprising a measuring unit for determining the mass flow rate of oxygen passing through said nozzle. Furthermore, the invention relates to a method for supplying oxygen to a person, in particular a flight passenger, using an oxygen breathing device.
摘要:
The invention relates to an oxygen breathing device that includes an oxygen source, in particular a chemical oxygen generator or an oxygen pressure tank, at least one oxygen mask connected via an oxygen supply line to said oxygen source, and a flow control unit adapted to receive a signal indicating ambient pressure or to detect ambient pressure and to control the flow of oxygen through the oxygen supply line depending on said ambient pressure. In some embodiments, the flow control unit is adapted to provide a low oxygen flow at a first ambient pressure and provide a higher oxygen flow at a second ambient pressure which is lower than said first ambient pressure.

The invention relates to an oxygen breathing device, in particular for cockpit crew member of an aircraft, comprising a pressurized oxygen source for storing pressurized oxygen, an oxygen mask, adapted to fit to nose and mouth of a person to be supplied with oxygen from the pressurized oxygen source, an oxygen supply line connecting the pressurized oxygen source with the oxygen mask, a pressure regulator/safety valve coupled in the oxygen supply line to selectively open or shut off oxygen flow from the pressurized oxygen source to the oxygen mask and/or to control pressure of said oxygen supplied to the oxygen mask. According to the invention, such oxygen breathing device is improved by having a pneumatic seal adapted to pneumatically seal the pressurized oxygen source in a non-use condition, an opening device adapted to open the pneumatic seal in case of an emergency situation requiring oxygen supply to the person, a change over valve adapted to selectively supply oxygen from the pressurized oxygen source or pressurized air from a pressurized air source to the oxygen mask.

Embodiments of the present invention provide a mounting bracket for use in connection with a rail, for assembling cabin interior components into an aircraft.
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.
摘要:
A cockpit oxygen mask includes a mask body, an oxygen inhalation valve, a mixed air inhalation valve, an exhalation valve as well as a control device. At least the oxygen inhalation valve is signal-connected to the control device. The oxygen inhalation valve is designed as an electromagnetically actuatable valve, and includes at least one through flow path which may be closed by a magnetically movable valve body, wherein the through flow path is limited by a magnetizable wall, and wherein the wall includes at least one discontinuous location which deforms a magnetic field produced in the wall.
