Abstract

Dans cet élément d'étanchéité, un ressort hélicoïdal 7 dont les spires sont disposées à une certaine distance les unes des autres est recouvert en totalité ou partiellement d'un élastomère 8, et lorsque la couche d'élastomère 8 est partielle, cette dernière est toujours disposée sur le côté du ressort hélicoïdal 7 soumis à la pression la plus élevée.In this sealing element, a helical spring 7 the turns of which are arranged at a certain distance from one another is covered in whole or in part with an elastomer 8, and when the elastomer layer 8 is partial, the latter is always arranged on the side of the coil spring 7 subjected to the highest pressure.
