Definitions

  • the present disclosure relates to a regulation assembly for a respiratory mask for an aircraft crew member.

  • the second position “100%” corresponds to “100%” mode. It offers protection against hypoxia.
  • the third position “N” corresponds to “NORMAL” mode. It makes it possible to limit oxygen consumption in preventive wear or on a landing in descent profile.

  • the selection button also has side markings to allow verification of the selected mode by a third party.
  • current respiratory masks include means providing information on the selected operating mode to the user, thanks to the asymmetry of the button, and to third parties, using the side markings.

  • the pressure in the cabin is substantially equal to the pressure outside the cabin and decreases until said pressurization pressure is reached.
  • the pressure in the cabin is then kept constant until the pressure outside becomes lower than the pressurization pressure.
  • the respiratory mask aims to allow its user to have sufficient oxygen and to be protected from harmful substances in the event of incidents, such as depressurization, presence of toxic gases or the like, preventing the occupants of the cabin from breathing normally .
  • the respiratory mask 100 includes a face cover 2 and a regulation assembly 1.

In the first operating mode, called “EMERGENCY" mode, the regulator supplies the breathing cavity 4 only with breathing gas until a slight excess pressure is reached in the breathing cavity 4 relative to the ambient pressure of the cabin air, generally this overpressure is between 3 mbar and 30 mbar. In the most common overpressure values, between 3 to 7 mbar, this overpressure value is hardly felt by the user. Beyond 10 to 12 mbar, the excess pressure requires a substantial additional effort from the user to breathe which is quickly felt by the user.

  • the regulator supplies the respiratory cavity 4 only with respiratory gas until it reaches substantially the ambient pressure.
