Abstract

Cet amortisseur (1) comporte : - une chambre d’amortissement (2), contenant un fluide visqueux (H), et équipée d’un piston (20) monté coulissant et muni de clapets à laminage définissant un premier tarage ; - au moins une chambre additionnelle (3) d’amortissement, contenant le fluide visqueux (H), et équipée d’un piston additionnel (30) monté fixe et muni de clapets à laminage définissant un tarage additionnel ; - un circuit hydraulique (C), reliant la chambre d’amortissement (2) à la chambre additionnelle (3) d’amortissement ; - un système de commande du circuit hydraulique (C), configuré pour : autoriser un écoulement du fluide visqueux (H) dans la chambre additionnelle (3) d’amortissement, de sorte que l’amortisseur (1) présente un tarage équivalent à la résultante du premier tarage et du tarage additionnel ; ou interdire un écoulement du fluide visqueux (H) dans la chambre additionnelle (3) d’amortissement, de sorte que l’amortisseur (1) présente un tarage équivalent au premier tarage.
