A demand regulator () for aircraft breathing device () comprising: &#x2014;a respiratory chamber () supplied with respiratory gas comprising breathable gas and dilution gas, &#x2014;a breathable gas supply line (), &#x2014;a dilution gas supply line (), &#x2014;a first adjusting device () of non-electrical type adjusting the pressure in the respiratory chamber (), and &#x2014;a second adjusting device (-) adjusting the rate of dilution gas in the respiratory gas supplied to the respiratory chamber (), the second adjusting device comprising a dilution valve () disposed in the dilution gas supply line (), a sensor (-) and an electrical control unit () adjusting the rate of dilution gas in the respiratory gas by controlling the dilution valve ().

Aircraft demand regulator and dilution regulation method

A method for determining a characteristic such as partial pressure or percentage of a gaseous constituent in a first gas mixture flow in a flow chamber in which there is alternating flow in opposite directions between the first gas mixture flow and a second gas mixture flow. The steps may include a) introducing the first gas mixture flow into a sensing chamber when the first gas mixture flow flows in the flow chamber, b) preventing introduction of gas from the flow chamber into the sensing chamber at least when the second gas mixture flow flows in the flow chamber, c) sensing the characteristic of the first gas mixture flow in the sensing chamber.

Oxygen regulator () to deliver breathing gas in a cabin () of an aircraft comprising a first inlet () for pressurized breathing oxygen, a second inlet () for diluter gas, an outlet () to provide a breathing mixture to a user, and a regulation device adjusting the concentration of breathing oxygen in the breathing mixture. The regulation device comprises a emergency device () that adjusts the concentration of breathing oxygen in the breathing mixture as a function of a variation speed of the cabin altitude.
