Abstract

L'invention concerne un amplificateur de force de freinage à dépression. Cet amplificateur comporte une enceinte 2 subdivisée en une chambre de travail 12 et une chambre à dépression 11 par une cloison mobile à membrane 6, 7, 9. A l'intérieur de cette enceinte est prévu un tube 3 à brides 4, 5 pour la fixation des deux parties de l'enceinte. La cloison coulisse de manière étanche sur le tube par un moyeu 8 et est fixée au boîtier 13 de la soupape de commande par des organes transversaux 20 passant dans des fentes 19 du tube Ce tube permet une plus grande rigidité de l'enceinte avec une construction moins coûteuse et moins lourde. L'invention s'applique aux amplificateurs de force de freinage à dépression pour véhicules automobiles.
