The invention relates to a valve system for a space (1) which is under vacuum in relation to its surroundings (3), which valve system comprises a valve unit (7) which is intended to be arranged in association with a wall (2) which delimits the said space and has a wall opening (4) through the said wall, which valve unit comprises a valve (8) which is normally shut and closes the said wall opening but is arranged to be opened and allow air from the surroundings into the said space if the vacuum, i.e. the difference between the surrounding pressure and the pressure in the space, should exceed a previously defined value. According to the invention, the external force, for keeping the valve (8) shut, is obtained from a pneumatic power source (34).
Système de soupape (7) destiné à un espace (1) sous vide par rapport à son environnement (3), et comprenant un ensemble soupape (7) se montant sur une paroi (2) délimitant ledit espace et percée d'un orifice (4). Ledit ensemble soupape comprend une soupape qui se trouve normalement en position fermée et obture l'orifice de la paroi, mais est conçue pour s'ouvrir et laisser rentrer l'air lorsque le différentiel de pression entre l'extérieur et l'intérieur de l'espace dépasse une valeur préétablie. Selon l'invention la force extérieure maintenant la soupape (8) en position de fermeture provient d'une source pneumatique (34).
