Title
(EN) SEALING DEVICE
(FR) DISPOSITIF D'ÉTANCHÉITÉ
Abstract
(EN) A sealing device (1) comprising a gasket (5) configured to seal a gap (2) between a first element (3) and a second element (4), wherein the gasket is arranged to be located in the gap (2) and to be in contact with the first and the second elements (3,4) during use, the sealing device comprising: a gasket (5) comprising two elongated gasket members (5a, 5b), where an inner 5 elongated gasket member (5a) is configured to surround an area (A), and an outer elongated gasket member (5b) is configured to surround the inner gasket (5a) and said area (A); and a carrier member (6), extending along the length of the elongated gasket members (5a,5b), and said elongated gasket members (5a,5b) being attached to the carrier member so that they are held in position on a distance from each other so as to form an intermediate gasket space (8) 10 between the gasket members (5a,5b); and a channel (7) connecting the intermediate gasket space (8) with the surroundings and being configured to be connected to a pressure source, to allow application of pressure on the intermediate gasket space (8) during use.
(FR) L'invention concerne un dispositif d'étanchéité (1) comprenant un joint d'étanchéité (5) configuré pour sceller un espace (2) entre un premier élément (3) et un deuxième élément (4), le joint d'étanchéité étant agencé de façon à être situé dans l'espace (2) et pour être en contact avec les premier et deuxième éléments (3, 4) pendant l'utilisation, le dispositif d'étanchéité comprenant : un joint d'étanchéité (5) comprenant deux éléments de joint allongés (5a, 5b), un élément de joint allongé intérieur (5a) étant conçu pour entourer une zone (A), et un élément de joint allongé extérieur (5b) étant conçu pour entourer le joint intérieur (5a) et ladite zone (A) ; et un élément de support (6), s'étendant le long de la longueur des éléments de joint allongés (5a, 5b), et lesdits éléments de joint allongés (5a, 5b) étant attachés à l'élément de support de sorte qu'ils soient maintenus en position à une certaine distance l'un de l'autre de façon à former un espace de joint intermédiaire (8) entre les éléments de joint d'étanchéité (5a, 5b) ; et un canal (7) reliant l'espace de joint intermédiaire (8) à l'environnement et étant configuré pour être relié à une source de pression, pour permettre l'application de pression sur l'espace de joint intermédiaire (8) pendant l'utilisation.
