Abstract

Le dispositif selon l'invention comporte un joint flexible annulaire 42 fixé à l'un des éléments 20 définissant une fente 28 avec un second élément extérieur 26, la dimension minimale de la fente étant limitée par les têtes de rivets 24 et l'anneau comportant des fentes etroites 46 pour former des doigts flexibles 48 venant sous l'action du fluide sous pression en contact d'obturation en 50 avec l'élément extérieur 26, l'anneau comportant des orifices constants 52 de façon que le débit à travers la fente 28 soit indépendant des variations de cette fente. Un tel dispositif convient en particulier pour régler le débit d'air de refroidissement dans un moteur à turbine à gaz.
