Abstract
(EN)
Partition member (22) of an anti-vibration hydraulic mount (14) comprising a first channel (26) and a second channel (28) between the working chamber (20) and the compensating chamber (25). The partition member (22) comprising a membrane (32) secured in a receiving cavity, the membrane (32) dividing the receiving cavity into two sub-spaces separated fluidically from each other. The membrane (32) comprises a closing device being able to have two configurations: an open configuration, the closing device being spaced apart from the central opening (42), and a closed configuration, the closing device abutting against the central opening (42) to close the central passageway.

L'invention concerne un élément de séparation (22) d'un support hydraulique anti-vibrations (14) comprenant un premier canal (26) et un second canal (28) entre la chambre de travail (20) et la chambre de compensation (25). L'élément de séparation (22) comprenant une membrane (32) fixée dans une cavité de réception, la membrane (32) divisant la cavité de réception en deux sous-espaces séparés de manière fluidique l'un de l'autre. La membrane (32) comprend un dispositif de fermeture étant apte à avoir deux configurations : une configuration ouverte, le dispositif de fermeture étant espacé de l'ouverture centrale (42), et une configuration fermée, le dispositif de fermeture butant contre l'ouverture centrale (42) pour fermer le passage central.
