Sur ce dessin, les figures 1 et 2 représentent en coupe diamétrale un bouchon muni d'une garniture selon l'invention, respectivement en position libre et en In this drawing, Figures 1 and 2 show in diametral section a plug provided with a gasket according to the invention, respectively in the free position and in
position de travail, comprimée.working position, compressed.
On a représenté sur ces figures un bouchon 10, de type traditionnel, qui doit être considéré comme un exemple générique de corps fileté à visser dans un siège, avec interposition d'une garniture: en effet, tout autre type de raccord a la même forme en ce qui concerne l'existence d'une tige filetée 11, décolletée à These figures show a plug 10, of the traditional type, which must be considered as a generic example of a threaded body to be screwed into a seat, with interposition of a fitting: indeed, any other type of fitting has the same shape as regards the existence of a threaded rod 11, turned to
proximité d'une face d'appui 12.proximity of a bearing face 12.
$ Selon l'invention, on réalise un élément annulaire 13 en une matière relativement rigide, métallique ou non, qui présente une saillie 14 sur sa face interne. A l'intérieur de cet élément est disposé un joint torique traditionnel 15. Il est à remarquer que l'épaisseur de l'anneau 13 est plus petite que le diamètre de la section du joint torique: cette épaisseur est égale à la dimension correspondante que le joint torique doit According to the invention, an annular element 13 is produced from a relatively rigid material, metallic or not, which has a projection 14 on its internal face. Inside this element is arranged a traditional O-ring 15. It should be noted that the thickness of the ring 13 is smaller than the diameter of the section of the O-ring: this thickness is equal to the corresponding dimension that the O-ring must

Sur la base de ce qui a été exposé, il est facile de comprendre les avantages de l'ensemble de garniture Based on what has been discussed, it is easy to understand the benefits of the packing assembly
proposé ci-dessus.proposed above.
Le joint torique maintient l'élément rigide 13 grâce à la saillie périphérique interne 14 de ce dernier et le montage de l'ensemble sur une tige filetée normale, de série, est simple et ttès rapide. Quand on effectue le serrage, l'élément 13, qui maintient périphériquement le joint torique en empêchant toute altération de sa forme et en uniformisant sa compression, constitue un limiteur de déformation limitant le rapprochement possible des The O-ring maintains the rigid element 13 thanks to the internal peripheral projection 14 of the latter and the assembly of the assembly on a normal threaded rod, as standard, is simple and very fast. When tightening is carried out, the element 13, which peripherally maintains the O-ring by preventing any alteration of its shape and by standardizing its compression, constitutes a deformation limiter limiting the possible approximation of the

Naturellement, la forme spécifique et les dimensions des éléments constituant la garniture peuvent varier, Naturally, the specific shape and dimensions of the elements constituting the lining may vary,
