Abstract

Ce dispositif d'étanchéification et de refroidissement entre deux pièces est constitué par une bande de métal 27 munie de fentes s'étendant longitudinalement et transversalement 28, 29, 30. La bande 27 est positionnée dans un vide 26 formé par deux évidements usinés respectivement dans chacune des faces vis-à-vis des pièces voisines. En fonctionnement, le fluide sous haute pression, agissant sur la bande, la force en contact avec le côté basse pression de la surface 35 du vide et assure une étanchéification efficace à l'interstice entre plateformes 36. Une petite partie du fluide sous haute pression est autorisée à traverser les encoches 28, 29, 30 pour assurer un refroidissement dans la région de l'interstice entre plateformes 36. (CF DESSIN DANS BOPI)This sealing and cooling device between two parts consists of a metal strip 27 provided with slots extending longitudinally and transversely 28, 29, 30. The strip 27 is positioned in a void 26 formed by two recesses machined respectively in each of the faces vis-à-vis neighboring parts. In operation, the high pressure fluid, acting on the belt, forces it into contact with the low pressure side of the surface 35 of the void and provides effective sealing at the gap between platforms 36. A small portion of the high pressure fluid is allowed to pass through the notches 28, 29, 30 to ensure cooling in the region of the gap between platforms 36. (CF DRAWING IN BOPI)
