Abstract

La présente invention a pour objet un dispositif de régulation de pression constituant une soupape dite absolue, comprenant un corps creux (1) de forme générale cylindrique d’axe XX’, un élément mobile (4) apte à se déplacer suivant l’axe XX’ dans le dit corps creux (1) et à former dans celui-ci une chambre étanche (3) complètement fermée ne comportant en opération aucune communication avec l’extérieur de son volume propre qui, en position de fermeture de l’élément mobile (4), est constant et indépendant de la température, une entrée (7) de gaz débouchant à l’intérieur du corps creux (1) par un orifice (13) disposé face à la face dite externe (15) de l’élément mobile (4), une sortie (8) de gaz communiquant avec l’intérieur du corps creux (1) par un orifice de décharge (12) qui débouche à l’extérieur de la paroi périphérique (19) de l’élément mobile (4), et un moyen (2) disposé dans celle-ci et appuyant sur la face dite interne (14) de l’élément mobile (4) suivant une force prédéterminée, lequel élément mobile (4) empêchant, en position de fermeture contre un appui avec lequel il assure l’étanchéité, toute communication entre l’entrée (7) et la sortie (8) tant qu’une force agissant sur la face externe (15) de l’élément mobile (4) ne soit suffisante pour s’opposer et vaincre la force du moyen (2) appuyant sur la face interne (14) de l’élément mobile (4) (2) et dégager celui-ci (4) de son appui, ouvrant alors la communication (24) entre l’entrée (7) et la sortie (8). Figure pour l'abrégé : 1The subject of the present invention is a pressure regulating device constituting a so-called absolute valve, comprising a hollow body (1) of generally cylindrical shape with axis XX', a movable element (4) capable of moving along axis XX ' in said hollow body (1) and to form in it a completely closed sealed chamber (3) not comprising in operation any communication with the outside of its own volume which, in the closed position of the movable element ( 4), is constant and independent of the temperature, a gas inlet (7) opening inside the hollow body (1) through an orifice (13) disposed facing the so-called external face (15) of the movable element (4), a gas outlet (8) communicating with the interior of the hollow body (1) via a discharge orifice (12) which opens outside the peripheral wall (19) of the movable element (4). ), and a means (2) disposed therein and pressing on the so-called internal face (14) of the movable element (4) according to a predetermined force, which movable element (4) preventing, in the closed position against a support with which it ensures sealing, any communication between the inlet (7) and the outlet (8) as long as a force acting on the external face (15) of the movable element (4) is sufficient to oppose and overcome the force of the means (2) pressing on the internal face (14) of the movable element (4) (2) and release the latter (4) from its support, then opening the communication (24) between the inlet (7) and the outlet (8).
