Abstract

L'invention concerne un bouchon de fermeture (10) conçu pour la tubulure fixe d'un contenant, notamment d'un radiateur de véhicule à moteur, lequel bouchon comprend une partie extérieure (16) et une partie intérieure (15). La partie extérieure (16) est pourvue d'un élément de fermeture (17) pour la tubulure du contenant et d'un élément de saisie (18) pivotant relativement à la tubulure du contenant. Entre cet élément de saisie et l'élément de fermeture (17) de la partie extérieure (16) du bouchon agit une sécurité antitorsion (19). La partie intérieure (15) du bouchon comporte une liaison d'écoulement entre l'intérieur et l'extérieur du contenant, ainsi qu'un dispositif de vanne (11) pour ouvrir et fermer cette liaison d'écoulement. L'objectif de l'invention est, lorsque la sécurité antitorsion du bouchon de fermeture est actionnée, d'y amener de manière simple et sans pertes inadmissibles la température ambiante à l'intérieur du contenant ou la pression régnant à l'intérieur du contenant. L'objectif est atteint par le fait que la sécurité antitorsion (19), qui peut être ou est rendue solidaire par précontrainte d'un ressort, est désolidarisée au moyen d'un mécanisme (14) thermique ou commandé par pression.
