Claims (3)

  1. Disjoncteur électrique comprenant un boîtier isolant et, disposés à l'intérieur, des contacts coopérants et un mécanisme pour ouvrir et fermer les contacts, ledit boîtier isolant comportant des moyens (410) de ventilation sensibles à la pression comprenant un élément formant soupape unidirectionnelle élastique et de forme allongée pour commander la ventilation des produits d'arcs gazeux depuis l'intérieur dudit boîtier et pour réduire au minimum la pénétration d'impuretés du milieu environnant, caractérisé en ce que lesdits moyens de ventilation comprennent une paire de fentes (412) de ventilation disposées côte-à-côte, s'étendant à travers une partie de paroi du boîtier et séparées l'une de l'autre par une barrière (414), et en ce que ledit élément (410) formant soupape unidirectionnelle est un élément unique commun aux deux fentes (412) de ventilation, qui se plie de façon élastique autour de ladite barrière (414) et comporte, de chaque côté de la barrière, des parties insérées dans les fentes respectives de façon à former une soupape unidirectionnelle dans chacune desdites fentes.
  2. Disjoncteur électrique selon la revendication 1, caractérisé en ce que lesdites fentes (412) de ventilation divergent l'une par rapport à l'autre dans la direction du flux gazeux les traversant.
  3. Disjoncteur électrique selon la revendication 1 ou la revendication 2, caractérisé en ce que lesdites fentes (412) de ventilation sont formées dans une partie de paroi d'un élément formant couvercle dudit boîtier et sont ouvertes vers un élément formant base dudit boîtier, sur lequel est monté de façon amovible ledit élément formant couvercle.
