Abstract

Machine (1) comportant un corps (2) avec au moins un cylindre (3), au moins un piston (4) monté dans l'alésage du cylindre, comportant au moins une gorge annulaire (4a) dans laquelle est disposé un segment (51, 52) annulaire d'étanchéité, caractérisée en ce que le piston (4) comprend deux parties (6, 7) montées l'une sur l'autre de manière amovible (8), déterminant entre elles un plan de joint (10) perpendiculaire à l'axe (11) du piston (4) et du cylindre (3), avec une seule gorge annulaire (4a) contenant le plan de joint (10), et un segment multiple (12) comprenant un empilement d'au moins deux segments (51, 52) d'étanchéité, continus selon leurs circonférences respectives, et délimités chacun entre deux bordures circulaires (51a, 51b, 52a, 52b), est monté à plat de manière libre dans la gorge (4a) entre les deux parties (6, 7) du piston. Les deux segments (51, 52) sont positionnés angulairement l'un par rapport à l'autre.
