Abstract

L'invention concerne un dispositif de contrôle du maintien d'un niveau de pression dans une enceinte (6) sous pression ou dépression, par rapport à la pression atmosphérique, qui est caractérisé en ce qu'il comporte un moyen localisé (5) plus déformable que ne l'est l'une quelconque des parois (1, 2) délimitant ladite enceinte, ledit moyen étant susceptible de passer d'une première géométrie lorsque la pression à l'intérieur de l'enceinte est du côté voulu d'un seuil prédéterminé à une deuxième géométrie lorsque la pression à l'intérieur de l'enceinte est de l'autre côté dudit seuil, l'une au moins desdites géométries étant observable depuis l'extérieur de l'enceinte.The invention relates to a device for controlling the maintenance of a pressure level in an enclosure (6) under pressure or depression, with respect to atmospheric pressure, which is characterized in that it comprises localized means (5) more deformable than any one of the walls (1, 2) delimiting said enclosure, said means being capable of passing from a first geometry when the pressure inside the enclosure is on the desired side of a predetermined threshold at a second geometry when the pressure inside the enclosure is on the other side of said threshold, at least one of said geometries being observable from outside the enclosure.
