Abstract
Un dispositif d'amortissement hydraulique (100) comprend un logement définissant une entrée de fluide et une sortie de fluide, une plaque d'amortissement (107) disposée à l'intérieur du logement, la plaque d'amortissement (107) comprenant une pluralité de trous d'amortissement (107a) définis à travers et positionnés pour permettre une communication fluidique entre l'entrée de fluide et la sortie de fluide, et un élément de blocage (109) disposé à l'intérieur du logement et conçu pour tourner par rapport à la plaque d'amortissement (107) pour bloquer progressivement les trous d'amortissement (107 a).
