Abstract

Piston (1, 1A) de cartouche constitué d'une matière sensible au contenu de la cartouche, qui comporte un disque de couverture (9, 9A) constitué d'une matière non sensible au contenu de la cartouche. Ce disque est placé sur la surface supérieure (5) du piston et possède une structure adaptée aux formes transversales de la surface supérieure (5) du piston. La zone du piston (1, 1A) orientée vers la paroi de la cartouche est constituée d'une rainure annulaire (2) en V qui forme sur son bord une lèvre d'étanchéité (3). Selon la présente invention, le diamètre externe du disque de couverture (9, 9A) est inférieur à celui du bord du piston (1, 1A) formant la lèvre d'étanchéité (3) et le bord du disque de couverture (9, 9A) est relié de manière étanche à la surface supérieure (5) du piston. Cette configuration permet d'une part de protéger le piston contre l'influence du contenu de la cartouche et d'autre part de garantir la fonction d'étanchéité du piston, même en cas de bombement de la cartouche.
