  • Circuit for supplying oxygen to aircraft passengers
    Patent number: 9272786
    Abstract: The invention relates to a circuit for supplying oxygen to aircraft passengers. According to the invention, the line (5) used to supply pressurized oxygen to the passenger masks (6) comprises a motorized pressure regulator (8) which can be actuated in response to a pressure control signal (10) provided by an electronic control unit (9) according to a signal (11) that is representative of the cabin pressure (12).

  • Dual-inlet selective flow regulating valve
    Patent number: 7637280
    Abstract: A fluid distribution and control valve for respiratory gas delivery systems. The valve has a body which is defined by four internal zones. Each zone is connectable to an external fluid circuit and a mobile structure. The mobile structure can move into four positions. The different positions of the mobile structure determine which of the zones are in fluid communication with each other. The valve may also be used to in a pilot's mask to supply oxygen to the pilot from a main source or from a secondary source.
