Abstract

Le dispositif comporte une chambre 22 constituée par une partie du passage de traversée 5 dans lequel est disposé le doigt de gant 15, élargie diamètralement. Un clapet 31 monté libre dans la chambre 22 autour du doigt de gant 15 est constitué par au moins deux lames élastiques 40 comportant des pièces d'appui d'extrémité 42 de forme tronconique. La chambre 22 comporte une paroi tronconique 25 contre laquelle viennent s'appuyer les pièces d'appui 42 du clapet 31 lorsqu'un fluide parcourt le passage de traversée 5. Ces pièces d'appui 42 se rapprochent alors pour assurer le maintien transversal du doigt de gant 15. Simultanément, le débit du fluide dans le passage de traversée 5 est réduit à une valeur très faible sinon nulle. (CF DESSIN DANS BOPI)
