Abstract

L'invention concerne un cric hydraulique pour voiture avec un piston qui peut se déplacer de façon étanche dans un cylindre, qui présente un trou limitant la course du piston. Le cric est caractérisé en ce que le piston 3 présente une rainure 12 circulaire, dans laquelle sont disposés deux joints d'étanchéité 13, 14, constitués en forme d'anneaux, d'élasticités différenciées, s'entourant l'un l'autre, dont celui qui est situé vers l'intérieur 13 est constitué d'une matière très élastique, celui situé à l'extérieur d'une matière non élastique. Application à tout vérin hydraulique où un joint d'étanchéité de piston doit se déplacer devant une lumière.
