Abstract

L'invention a trait à un ensemble joint d'étanchéité pour une pompe à additif comportant un piston alternatif. L'ensemble joint d'étanchéité comprend un porte-joint comportant un premier et un deuxième élément, chacun ayant un alésage pour recevoir le piston. Chaque élément comporte une surface d'extrémité disposée pour s'abouter l'une contre l'autre lorsqu'elles sont placées axialement sur le piston, et un joint mécanique est interposé entre les surfaces d'extrémité pour y empêcher la sortie du fluide. Une paire de joints circonférentiels à des emplacements espacés axialement sont fournis le long du porte-joint et peuvent être actionnés pour entrer en prise avec le piston durant le mouvement alternatif de celui-ci, et un orifice de fuite croisant un des alésages en position intermédiaire entre les joints est fourni pour permettre la sortie du fluide entre les joints.
