Description


   <EMI ID=1.1> 

  
Il est difficile de maintenir plane une membrane de caoutchouc serrée entre deux brides lorsqu'elle est utilisée dans un dispositif tel que sur l'une des faces de cette membrane agisse, en régime, une pression assez élevée. Les surfaces entre.lesquelles la membrane est enserrée doivent alors être serrées fortement et en pratique on a constaté que la membrane est alors

  
 <EMI ID=2.1> 

  
une membrane qui peut être bien serrée tout en conservant sa forme initiale plane après mise on place. A cet effet une telle membrane comporte, sur sa périphérie, un bord métallique et la partie de la membrane adjacente à ce

  
 <EMI ID=3.1> 

  
membrane, est en saillie par rapport à la surface de limitation du bord métallique qui se trouve du même côté de la membrane que la dite surépaisseur.

  
 <EMI ID=4.1> 

  
 <EMI ID=5.1> 

  
le joint proprement dito On constate qu'après le serrage, la membrane ellemême ne comporte aucune déformation. 

  
Bans une forme de réalisation de l'invention du côté opposé au bord métallique la surface de limitation de la surépaisseur est pratiquement perpendiculaire au plan de la membraneo Cette disposition améliore la quali-  té du joint lorsque la membrane est en place.

  
De préférence, dans une forme de réalisation de l'invention,

  
le bord métallique a une section rectangulaire. 

  
Dans une formé de réalisation préférentielle de l'invention, la membrane est en caoutchouc et elle est assemblée au bord par vulcanisation.

  
 <EMI ID=6.1> 

  
La description qui va suivre en regard du dessin annexé-, donné à titre d'exemple non limitatif, fera bien comprendre comment l'invention peut être réalisée, les particularités qui ressortent tant du texte que du dessin faisant, bien entendu, partie de ladite invention.

La Fig. 1 représente une membrane de fabrication connue. 

  
La Fig 2 représente une membrane conforme à l'invention entourée d'un bord métallique. 

  
La Fig. 3 représente une membrane dont le bord métallique a la

  
 <EMI ID=7.1> 

  
Sur la Fig. 1, la membrane 1 en caoutchouc est enserrée entre deux brides 2 et 3 et, sur l'une des faces de la membrane, règne une pression plus élevée que sur l'autre face; les brides doivent donc être convenablement serrées pour assurer un joint étanche., Après mise en place, la membrane prend une forme telle que la partie 1 semble plus épaisse que la partie 4 écrasée entre les brides 2 et 3 et de plus, la partie 1 est déformée. Sur la Fig. 2, la membrane 5 comporte une surépaisseur 6. Le bord 7 de la membrane est em-

  
 <EMI ID=8.1> 

  
entre les brides 9 et 10 représentées en pointillés, ces brides ne pressent que le bord 8 tandis que la surépaisseur 6 est déformée de façon à former le joint proprement dit. La membrane elle-même reste plane et conserve partout la même épaisseur.

  
Dans la forme de réalisation représentée sur la Fig. 3, la membrane comporte une surépaisseur 6 et le bord métallique 11 s'applique contre la périphérie de la membrane. La membrane est fixée par vulcanisation au bord métallique 11; ici aussi, les brides 9 et 10 serrent le bord métallique 11 et le joint s'obtient par la déformation de la surépaisseur 6.

  1. RESUME
    1. - Membrane réalisée en une matière élastique imperméable telle que le caoutchouc, caractérisée par le fait que sur sa périphérie, elle comporte un bord métallique et que la partie adjacente à ce bord présente une surépaisseur qui, lorsque la membrane n'est pas en place, est en saillie par rapport à la surface de limitation du bord métallique qui se trouve du même côté de la membrane que ladite surépaisseur. <EMI ID=9.1>
    pouvant présenter en outre les particularités suivantes prises séparément ou. suivant les diverses combinaisons possibles :
    a) du côté opposé au bord, la surface de limitation de la surépaisseur est perpendiculaire ou pratiquement perpendiculaire au plan de la membrane; b) le bord métallique a une section rectangulaire; c) la membrane est en caoutchouc et est fixée au bord par vulcanisation.
