Abstract
Coupelle d'étanchéité. La coupelle comporte un corps central annulaire à partir duquel sont définies une lèvre extérieure et une lèvre intérieure. La coupelle est logée dans une gorge annulaire d'un piston monté coulissant dans un alésage. La lèvre extérieure est inclinée par rapport à l'axe de la coupelle pour venir au contact de l'alésage selon une première portion de surface cylindrique d'étanchéité. Le corps annulaire est déformable sous l'action d'une différence de pression entre les deux faces de la coupelle, pour venir au contact de l'alésage de manière à constituer une deuxième portion de surface cylindrique d'étanchéité Application aux dispositifs d'étanchéité, en particulier pour maître-cylindre.
