Abstract

Le segment de piston suivant la présente invention comporte au moins un moyen de pompage comprenant une cavité hydrodynamique 16 dans une face latérale du segment 12. La cavité hydrodynamique emprisonne l'huile et le moyen de pompage refoule l'huile vers le côté inférieur du segment et hors de la rainure dans laquelle se trouve le segment jusqu'à l'espace libre compris entre le piston et l'alésage 10 du cylindre.
