Abstract

Piston pour amortisseur de chocs. L'ensemble formé par le piston d'un amortisseur hydraulique comprenant un ou plusieurs tubes est prévu pour être monté à l'extrémité d'une tige de piston alternative pour véhicule automobile. L'ensemble formé par le piston comprend un premier ensemble formant piston 42 et un second ensemble formant piston 42', disposés coaxialement, chacun comportant radialement des jeux d'orifices s'étendant axialement situés intérieurement 46 et 46' et extérieurement 44 et 44', un ensemble à clapets de compression adjacent à un côté d'un des organes formant piston et un ensemble à clapets de détente adjacent à un côté de l'autre organe formant piston. Piston pour amortisseurs de chocs pour véhicules automobiles.Piston for shock absorber. The assembly formed by the piston of a hydraulic shock absorber comprising one or more tubes is designed to be mounted at the end of a reciprocating piston rod for a motor vehicle. The piston assembly comprises a first piston assembly 42 and a second piston assembly 42 ', disposed coaxially, each radially comprising sets of axially extending orifices located internally 46 and 46' and externally 44 and 44 ' , a compression valve assembly adjacent to one side of one of the piston members and an expansion valve assembly adjacent to one side of the other piston member. Piston for shock absorbers for motor vehicles.
