Abstract: front page image
(EN)An annular sealing ring arranged to be mounted between the mutually facing wall surfaces of the ends of two pipe-like elements, one of which is inserted in the other. Figure 6 illustrates an annular seal having a rectangular cross-section such as to present two broad sides (14 and 15). Arranged closely adjacent one another are two parts (8" and 9"), one being for the supply of a hardenable substances to the internal cavity of the seal, and the other for the evacuation of air from said cavity. To prevent the hardenable substance from flowing in both directions around the cavity of the seal, a partition wall is formed between said parts, by pinching together the parts (19", 19"") of the annulars located therebetween, by means of a suitable tool (27). In this way, all air present in the cavity is evacuated therefrom without impeding the flow of said substance therearound.
(FR)Un joint d"etancheite annulaire concu pour etre monte entre les surfaces des parois des extremites de deux tuyaux semblables montes en vis-a-vis, l"un d"eux etant insere dans l"autre. La figure 6 illustre un anneau d"etancheite ayant une section rectangulaire telle qu"elle presente deux cotes larges (14 et 15). Deux parties (8" et 9") sont disposees l"une a cote de l"autre et servent, l"une, a l"alimentation en une substance durcissante dans la cavite interne du joint, l"autre, a l"evacuation de l"air de ladite cavite. Pour empecher la substance durcissante de couler dans les deux sens autour de la cavite du joint, une paroi de separation est formee entre les deux parties (8" et 9") par pincement des parties (19", 19"") des sections annulaires ou moyen d"un outil approprie (27). De cette maniere, l"air se trouvant dans la cavite est evacue sans entraver l"ecoulement circulaire de ladite substance.
