Abstract
Absorbeur de chocs hydraulique. Il comprend des tubes intérieur et extérieur montés coulissants l'un par rapport à l'autre et un orifice variable en fonction du mouvement relatif des deux tubes. Une entretoise tubulaire de grand diamètre est disposée coaxialement autour de la partie supérieure du tube externe pour ménager un espace entre le tube externe et l'entretoise, cet espace étant divisé par une membrane tubulaire coaxiale en une chambre pour gaz à haute pression disposée à l'extérieur de la membrane et une chambre pour gaz à pression réduite disposée à l'intérieur de la membrane et communiquant avec un espace supérieur interne au tube externe. Application à la réalisation d'amortisseurs pour véhicules automobiles.
