Abstract

Le problème décrit par la présente invention est d'augmenter la capacité d'un élément d'étanchéité de piston à se conformer aux évidements et aux saillies de la paroi intérieure d'un réservoir dans un dispositif d'alimentation en matériau visqueux, permettant ainsi d'empêcher des fuites de matériau visqueux à partir d'espaces dans l'élément d'étanchéité. La solution selon l'invention consiste, pour un matériau visqueux (M), à être placé dans un sac (B) fabriqué à partir d'un film de résine synthétique, et stocké dans un réservoir (2), la partie d'extrémité ouverte du sac (B) étant repliée sur la partie circonférentielle extérieure du réservoir (2) et fixée à celle-ci. Le matériau visqueux (M) est mis sous pression à l'aide d'un piston (3) introduit dans le sac (2), et est extrudé à partir d'un passage d'admission (16) prévu dans le piston (3). L'intervalle entre le réservoir (2) et le piston (3), le sac (B) étant disposé entre ceux-ci, est rendu étanche au moyen d'un élément d'étanchéité (13) comprenant une mousse de résine synthétique. Le diamètre extérieur de l'élément d'étanchéité (13) est supérieur au diamètre intérieur du réservoir (2), et l'élément d'étanchéité (13) est poussé élastiquement contre la paroi intérieure du réservoir (2), le sac (B) étant disposé entre ceux-ci. Ainsi, la capacité de l'élément d'étanchéité (13) à se conformer à la paroi intérieure du réservoir (2) est accrue, et y compris si le sac (B) subit des dommages, le matériau visqueux (M) ne fuit pas à partir de l'élément d'étanchéité (13).
