Abstract

Un piston d'une machine à déplacement volumétrique comporte une tête conique (1) pourvue d'un épaulement de butée (6) sur sa face terminale (5) d'un plus faible diamètre. L'autre face terminale (3) de la tête est reliée à une bielle (4). Une bague d'étanchéité élastique (8) est montée mobile sur la tête (1) le long de l'axe de cette dernière et entre les butées ménagées sur ladite tête, l'une d'elles étant l'épaulement (6) et l'autre étant une partie de la surface latérale (2) de la tête (1) située au niveau de la face terminale (3) d'un diamètre supérieur.
