Abstract

L'invention concerne un couvercle de fermeture destiné à une ouverture de radiateur de véhicule automobile. Le couvercle présenté comporte une partie intérieure (4) qui présente une liaison d'écoulement entre l'intérieur du contenant et l'extérieur du contenant, ainsi qu'un dispositif à soupapes (5) servant à libérer ou à bloquer la liaison d'écoulement. Le dispositif à soupapes (5) comprend un premier (7) et un second (8) élément d'obturation pouvant être déplacés, selon un mouvement de va-et-vient, entre une position de libération et une position de blocage. Le premier élément d'obturation (7) est soumis à une précontrainte en direction de l'intérieur du contenant et pressé dans cette direction, contre un premier siège d'étanchéité (13), se trouvant sur la partie intérieure (4), et sur un deuxième siège d'étanchéité (14), s'étendant radialement à l'intérieur du premier siège d'étanchéité (13), sur le second élément d'obturation (8). Lorsqu'une première valeur limite de la pression intérieure du contenant est dépassée, ledit premier élément d'obturation peut être soulevé de la partie intérieure (4) et, lorsqu'une valeur limite de sécurité de la pression intérieure du contenant est dépassée, il peut être soulevé de la partie intérieure (4) et du second élément d'obturation (8), chaque fois en libérant une liaison d'écoulement entre l'intérieur du contenant et l'extérieur du contenant. Le second élément d'obturation (8) se présente sous la forme d'un composant s'étendant transversalement par rapport au sens de déplacement des corps d'obturation (7, 8), ce composant présentant une ouverture (15) s'étendant radialement à l'intérieur du deuxième siège d'étanchéité (14) du premier élément d'obturation (7) et se trouvant en liaison d'écoulement avec l'intérieur du contenant. A ce composant est associé radialement, à l'extérieur du second siège d'étanchéité (14) du premier élément d'obturation (7) et en direction de l'extérieur du contenant, un troisième siège d'étanchéité (26) se trouvant sur la partie intérieure (4), contre lequel il vient s'appuyer lorsqu'une troisième valeur limite de la pression intérieure du contenant, se trouvant entre la première et la seconde valeur limite, est atteinte, ce qui entraîne le blocage d'une liaison d'écoulement entre l'intérieur du contenant et l'extérieur du contenant qui existait jusqu'ici.
