    摘要: There is produced (at 2) air enriched in inert gas, from a source (9) of compressed air internal to the aircraft, and this enriched air is admitted (via 10) into the fuel tank (12). During the cruising phase of the aircraft, there is produced a first fraction of air having a first inert gas content, and this first fraction is admitted into the fuel tank (12) at a first flow rate. Moreover, during the descent phase, there is produced a second fraction of enriched air having a second inert gas content substantially less than the first content, and the second fraction is admitted to the reservoir (12) at a second flow rate substantially greater than the first flow rate.

    摘要: A gas generator assembly, which is especially suited to both transportable and on-board oxygen generators, with at least one adsorbent and a buffer tank to store product gas separated from a feed gas mixture. In order to make the assembly squat and compact, the buffer tank may be of an annular or quadruple U shaped configuration. Such a buffer tank configuration may also provide the assembly with improved structural and protective attributes.

    摘要: The self-contained oxygen generator, of the type with a PSA unit (3), includes, in the outlet line (5), a flowmeter (13) providing a signal (14) representative of the flow rate of oxygen circulating in the outlet line, the latter being connected to a leakage circuit (15) comprising a calibrated orifice (17) and a solenoid valve (16) actuated in response to a signal (18) derived from the flow rate signal (14) provided by the flowmeter and organizing a calibrated leakage at the outlet from the PSA unit in the case of too low an oxygen consumption.
