Abstract

Joint de piston de cylindre de frein pour véhicule ferroviaire. Il comprend un anneau 6 en matière élastique, enclenché sur un rebord 1' d'un piston 1 et présentant, à sa surface orientée vers la paroi du cylindre 2, une gorge circonférentielle logeant une bande 7 en matière plus rigide que celle constituant l'anneau 6. Cette bande 7 entoure l'anneau radialement à l'extérieur du rebord 1' du piston. Domaine d'application : cylindres de freins de véhicules ferroviaires.Brake cylinder piston seal for rail vehicle. It comprises a ring 6 of resilient material, engaged on a rim 1 'of a piston 1 and having, on its surface oriented towards the wall of the cylinder 2, a circumferential groove housing a strip 7 of a material more rigid than that constituting the ring 6. This band 7 surrounds the ring radially outside the rim 1 'of the piston. Field of application: brake cylinders for railway vehicles.
