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.



   <EMI ID = 1.1>

  
It is difficult to keep flat a rubber membrane clamped between two flanges when it is used in a device such that on one of the faces of this membrane acts, under operating conditions, a fairly high pressure. The surfaces between which the membrane is clamped must then be tightened strongly and in practice it has been found that the membrane is then

  
 <EMI ID = 2.1>

  
a membrane which can be tightened while retaining its initial flat shape after placement. For this purpose, such a membrane comprises, on its periphery, a metal edge and the part of the membrane adjacent to this

  
 <EMI ID = 3.1>

  
membrane, is protruding from the limiting surface of the metal edge which is on the same side of the membrane as said extra thickness.

  
 <EMI ID = 4.1>

  
 <EMI ID = 5.1>

  
the seal proper o It is noted that after tightening, the membrane itself does not have any deformation.

  
In one embodiment of the invention on the side opposite the metal edge, the excess thickness limiting surface is practically perpendicular to the plane of the membrane. This arrangement improves the quality of the seal when the membrane is in place.

  
Preferably, in one embodiment of the invention,

  
the metal edge has a rectangular section.

  
In a preferred embodiment of the invention, the membrane is made of rubber and it is assembled to the edge by vulcanization.

  
 <EMI ID = 6.1>

  
The description which will follow with regard to the appended drawing, given by way of nonlimiting example, will make it clear how the invention can be implemented, the particularities which emerge both from the text and from the drawing being, of course, part of said invention.

Fig. 1 shows a membrane of known manufacture.

  
Fig 2 shows a membrane according to the invention surrounded by a metal edge.

  
Fig. 3 shows a membrane whose metallic edge has the

  
 <EMI ID = 7.1>

  
In Fig. 1, the rubber membrane 1 is clamped between two flanges 2 and 3 and, on one side of the membrane, a higher pressure prevails than on the other side; the flanges must therefore be suitably tightened to ensure a tight seal., After installation, the membrane takes a shape such that part 1 seems thicker than part 4 crushed between flanges 2 and 3 and, moreover, part 1 is distorted. In Fig. 2, the membrane 5 has an extra thickness 6. The edge 7 of the membrane is em-

  
 <EMI ID = 8.1>

  
between the flanges 9 and 10 shown in dotted lines, these flanges only press the edge 8 while the extra thickness 6 is deformed so as to form the seal proper. The membrane itself remains flat and maintains the same thickness everywhere.

  
In the embodiment shown in FIG. 3, the membrane has an extra thickness 6 and the metal edge 11 is applied against the periphery of the membrane. The membrane is fixed by vulcanization to the metal edge 11; here too, the flanges 9 and 10 clamp the metal edge 11 and the seal is obtained by the deformation of the extra thickness 6.
