| 摘要 |
The subject of the invention is a method and device for regulating the flow rate of at least two gases A, B by means of restrictions 3, 4 in which the pressure difference between the inlet and outlet of each restriction 3, 4 is directly proportional to the flow rate of each of the gases A, B, the said restrictions 3, 4 consisting of an amalgam of microballs or microwires, the bundling or compacting of which generates different permeabilities on each inlet 1, 2 in such a way as to obtain different gas flow rates at different pressure differences between inlet and outlet of the said restrictions 3, 4 allowing, by means of a pressure regulator with a membrane 6 and a valve 7 driven by one of the gases, to keep the chosen proportionality of the gas flow rates A, B by maintaining equal pressures at each inlet of the restrictions 3, 4. <IMAGE>
