Abstract

L'amortisseur, déformable avec la suspension du véhicule, est monté entre une partie suspendue 1 et une partie non suspendue 2. Des moyens sont prévus, tels qu'un piston percé de compensation 12, pour permettre une déformation lente du corps de l'amortisseur, pour compenser une déformation lente de la suspension. Des moyens de rappel, tels qu'un ressort 14, maintiennent au repos le piston d'amortissement 5, dans une position prédéterminée, en regard d'une zone 5B de la paroi interne du corps cylindrique 3. Des moyens de blocage, tels qu'un clapet d'obturation automatique du piston 12, bloquent toute déformation du corps 3 de l'amortisseur, lorsque la vitesse de déformation du corps tend à dépasser une valeur limite. Application aux amortisseur de véhicules, pour maintenir des valeurs équilibrées A1, A2, de la course d'amortissement dans chaque sens, malgré des variations C1, C2, de longueur au repos, pouvant résulter de diverses valeurs de la charge et du centrage du véhicule.
