Abstract

Selon l'invention, l'usure d'un élément de scellement assurant un scellement entre un joint femelle et un joint mâle, est atténuée. Un élément de scellement de face extrémité est disposé sur une partie épaulement circulaire à l'intérieur d'un trou traversant d'un clapet à bille maintenu par un élément enveloppe de manière à permettre une rotation autour d'une ligne d'axe central de rotation, et une face extrémité avant du joint mâle introduit à l'intérieur du trou traversant pousse cet élément de scellement de face extrémité. Lorsque le joint mâle est introduit à l'intérieur dudit trou traversant, et est mis en rotation avec pour centre ladite ligne d'axe central de rotation suivant une partie ouverture de fente de l'élément enveloppe, et que le joint mâle est mis en une position raccordement, alors une partie bord d'accouplement des deux côtés de l'ouverture de fente accouplée avec le joint mâle, glisse et s'accouple avec le joint mâle, pousse graduellement le joint mâle dans la direction dudit élément de scellement de face extrémité, et un accouplement hermétique est ainsi effectué entre le clapet à bille et le joint mâle du fait de la poussée de l'élément scellement de face extrémité par la face extrémité avant du joint mâle sur la partie épaulement circulaire, lorsque le joint mâle est en une position raccordement.
