Abstract

Un système pour séparer un composant à partir d'un mélange de fluide pour produire un fluide respirable en dirigeant alternativement le mélange de fluide vers un premier ou un deuxième tamis moléculaire en matériau adsorbant. Des valves de commande coopèrent avec chacun des tamis pour autoriser l'admission de fluide sous pression à partir d'un conduit d'alimentation vers l'un des tamis et provoquent une augmentation de pression dans le tamis et dans le conduit d'alimentation. Un dispositif de commande délivre un premier et un second signal de commande qui contrôlent la communication de fluide du conduit d'alimentation avec le premier et le second tamis respectivement. Les premier et second signaux se chevauchent pendant un intervalle de temps au cours duquel il se produit une égalisation de pression entre le premier et le second tamis, par l'intermédiaire d'une valve d'égalisation. Un détecteur de pression engendre un signal de commutation chaque fois que la pression dans le conduit d'alimentation excède une valeur prédéterminée. En réponse à la succession de signaux de commutation, les premier et deuxième signaux de commande sont alternativement engendrés.
