Abstract

Compresseur à mouvement alternatif destiné aux très hautes pressions comprenant d'une part au moins un piston plongeur ou une chemise de cylindre constituée d'un matériau choisi parmi les fontes, les aciers et les carbures de tungstène et d'autre part au moins un élément d'étanchéité. L'élément d'étanchéité est constitué d'un matériau composite associant d'une part au moins un alliage métallique choisi parmi les bronzes et les alliages à base de titane et d'autre part soit au moins un polymère choisi parmi les polytétrafluoréthylènes, les polyimides et les polymides-amides, soit un composé fritté graphite-argent. Application à la compression d'un fluide sous une pression de refoulement supérieure ou égale à 150 bars.
