Abstract

La présente invention concerne la structure d'un piston formant crémaillère destiné à être utilisé dans un dispositif hydraulique tel qu'un dispositif de fermeture de porte. Ce piston est caractérisé en ce qu'il est constitué d'une seule pièce formée par une crémaillère métallique et un joint d'étanchéité en résine synthétique. Applicable aux dispositifs de fermeture de portes.
