Abstract
La présente invention concerne un appareil à commander un écoulement d'agent de pression. Appareil caractérisé en ce qu'à l'entrée 10 d'agent de pression est disposé un régulateur de pression ou d'écoulement 12, en ce qu'à chacune des branches mentionnées 20A à 28A est adjointe une branche de désaération 20E à 28E, dans laquelle est disposé un étrangleur 20F à 28F dont la résistance à l'écoulement est égale à celle de l'étrangleur 20C, 20D à 28C, 28D de la branche principale correspondante 20 à 28, en ce que les valves 20G à 28G sont disposées en aval des étrangleurs, et sont sous la forme de distributeurs, chacune d'entre elles permettant d'établir une liaison, de la sortie du régulateur 12 à la branche principale ou à la branche de désaération correspondante. L'invention est plus particulièrement applicable à la distribution de gaz inerte de protection dans la spectroscopie d'absorption atomique sans flamme.
