Abstract
L’invention concerne un porte-diaphragme pour amortisseur de type oléopneumatique, comprenant un corps tubulaire réalisé en matière thermoplastique ayant une première extrémité agencée pour porter un diaphragme pourvu d’orifices de restriction d’écoulement et une deuxième extrémité opposée définissant un fond agencé pour supporter des efforts de pression. Selon l’invention, chacune des deux extrémités est pourvue d’un élément de renforcement mécanique localisé formant une butée axiale agencée pour permettre une sollicitation en traction du corps tubulaire.
