A rotary valve system which includes of a pair of valve assemblies each of whichhas valve parts with flat faces which, when pressed together and rotated, provide valving action between various ports incorporated in one valve part of each assembly. The first valve part of each assembly contains a circular array of through openings, each of which is connected to a conduit. The second valve part of a first assembly or of each assembly contains several passages which provide communication between various openings of the first valve part and valve apertures located in the second valve part of each assembly. The second valve part of the first assembly also contains one or more passages which provide communication between members of one or the other array of openings. The valve system can be effectively used to automate operation of a gas or liquid adsorption system comprising two or more adsorption vessels, the number of vessels being equivalent to the total number of openings in either array. Use of the valve assembly in anadsorption system eliminates the need for many of the valves required in conventional multivessel adsorption systems.

Système de tiroir tournant comprenant une paire d'ensembles de tiroirs comprenant chacun des pièces à faces plates qui, lorsqu'elles sont serrées l'une contre l'autre puis mises en rotation, assurent une action de communication et d'obturation entre divers orifices intégrés à une pièce de chaque ensemble. La première partie tiroir de chaque ensemble contient une série circulaire d'orifices de part en part, chacun étant relié à un conduit. La deuxième partie tiroir d'un premier ensemble ou de chaque ensemble, contient plusieurs ensembles qui assurent la communication entre les diverses ouvertures de la première partie tiroir et des lumières dans la deuxième partie tiroir de chaque ensemble. La deuxième partie tiroir du premier ensemble contient également un ou plusieurs passages qui assurent la communication entre les éléments de l'un ou de l'autre ensemble d'ouvertures. Le système de tiroir peut être efficacement utilisé pour automatiser le fonctionnement d'un système d'adsorption de gaz ou de liquides comprenant au moins deux enceintes d'adsorption, le nombre d'enceintes étant égal au nombre total d'ouvertures dans l'une ou l'autre série. L'utilisation de l'ensemble tiroir dans un système d'adsorption élimine les nombreux appareils de robinetterie requis dans les systèmes conventionnels d'adsorption à enceintes multiples.
