Abstract
(EN)
This vibration-damping device (1) is equipped with an outer tube (11), an inside member (12), an elastic body (13), a partition member (17), an intermediate tube (31), and a delimiting member (32). The elastic body couples the outer tube and the inside member. The partition member partitions a liquid chamber (14) inside the outer tube into a main liquid chamber (15) and an auxiliary liquid chamber (16). An orifice passage (21) is formed in the partition member. The intermediate tube (31) is arranged between the outer tube and the inside member, and is coupled to the elastic body. The delimiting member is coupled to the intermediate tube, and partitions the main liquid chamber into a first main liquid chamber (15a) and a second main liquid chamber (15b). A housing chamber (37), first connecting holes (37a), and second connecting holes (37b) are formed in the delimiting member. A movable member (36), which is displaced or deformed in response to a pressure difference between the first main liquid chamber and the second main liquid chamber, is housed inside the housing chamber.

L'invention concerne un dispositif d'amortissement de vibrations (1) équipé d'un tube extérieur (11), d'un élément intérieur (12), d'un corps élastique (13), d'un élément de séparation (17), d'un tube intermédiaire (31) et d'un élément de délimitation (32). Le corps élastique accouple le tube extérieur et l'élément intérieur. L'élément de séparation sépare une chambre de liquide (14) à l'intérieur du tube extérieur en une chambre de liquide principale (15) et une chambre de liquide auxiliaire (16). Un passage d'orifice (21) est formé dans l'élément de séparation. Le tube intermédiaire (31) est disposé entre le tube extérieur et l'élément intérieur, et est accouplé au corps élastique. L'élément de délimitation est accouplé au tube intermédiaire, et sépare la chambre de liquide principale en une première chambre de liquide principale (15a) et une seconde chambre de liquide principale (15b). Une chambre de logement (37), des premiers trous de raccordement (37a) et des seconds trous de raccordement (37b) sont formés dans l'élément de délimitation. Un élément mobile (36), qui se décale ou se déforme en réponse à une différence de pression entre la première chambre de liquide principale et la seconde chambre de liquide principale, est logé à l'intérieur de la chambre de logement.
