Abstract

L'invention concerne un amortisseur de chocs hydrauliques télescopiques. Cet amortisseur comporte deux cylindres coaxiaux 10, 12 fermés par un manchon commun 14 comportant un alésage avec une portion de faible diamètre 32 servant au passage de la tige de piston 26 et une portion de diamètre plus grand 34 servant de puits pour recueillir le fluide fuyant dans le jeu entre tige et alésage 32. Le puits 34 communique avec l'espace intermédiaire 22 entre les deux cylindres par des passages 52 inclinés dont l'orifice est espacé du fond du puits pour assurer la présence d'une couche de fluide dans le fond du puits évitant l'introduction d'air dans le cylindre intérieur. L'invention s'applique aux amortisseurs de chocs hydrauliques pour véhicules automobiles.
