Abstract

Ce piston est du type de ceux qui sont munis d'un système d'étanchéité périphérique agissant dans le sens radiaL Le piston selon l'invention est fait d'une matière plastique présentant de bonnes qualités de glissement et une résistance mécanique suffisante pour résister aux pressions existantes sans déformation inadmissible, par exemple du polyuréthane renforcé de fibres de verre, et le système d'étanchéité périphérique est constitué par au moins une, mais de préférence deux lèvres annulaires 131, 132 de matière plastique, présentant l'élasticité d'un ressort et un profil conique. On obtient ainsi un piston de poids et de volume réduit, ce qui réduit le travail d'amortissement à fournir aux points morts, et qui, en raison du matériau utilisé, a un faible coefficient de friction.
