Abstract

L'invention concerne un amortisseur d'oscillations réglable (1) comprenant au moins une soupape d'amortissement réglable (33, 35) pour chaque sens de mouvement de travail de l'amortisseur d'oscillations, chaque soupape d'amortissement (33, 35) étant raccordée à une chambre de travail (37, 39) au moyen d'un raccord haute pression (67, 69) et à un accumulateur (49) au moyen d'un raccord basse pression (107, 109). Les deux soupapes d'amortissement réglables (33, 35) sont disposées dans un boîtier commun (31) présentant une chambre de raccordement (59) pourvue d'une ouverture de liaison (53, 55) vers respectivement une chambre de travail (37, 39) et d'un raccord (57) vers l'accumulateur (49), séparé de l'ouverture de liaison.
