Method and apparatus for mixing gases |
摘要 |
A method of accurately mixing gases in desired proportions which comprises establishing the gases to be mixed at a uniform pressure; sequentially feeding the gases through a common restrictor for proportionate time periods to give the gas mix desired. The apparatus used includes an isobaric gas reservoir unit which adjusts all gases to be mixed to have a common pressure; electronically actuated rapid response fluidic interface valves; a common restrictor through which the gases are passed to a rceiving and mixing chamber; and timing means controlling the valves to allow gases to be sequentially passed therethrough for pre-set time periods
