Abstract

L'invention concerne un antivibrateur (10) pouvant réduire au minimum le transfert de forces vibratoires d'un corps vibrant à un corps isolé (14). L'antivibrateur (10) comprend un boîtier (16) constitué d'éléments du boîtier (18, 20 et 22) reliés de manière souple les uns aux autres pour délimiter un premier réservoir (30), un second réservoir (32) et un port (34). Le port (34) relie le réservoir (30) au second réservoir (32) et peut être déplacé relativement à ces derniers, de façon à changer le volume des réservoirs en réponse à un mouvement relatif entre le corps vibrant et le corps isolé (14), le long d'un axe du boîtier. Une masse fluidique est présente dans le premier réservoir (30), le second réservoir (32) et le port (34); et l'antivibrateur (10) comprend deux diaphragmes de réglage (36 et 40) fonctionnant dans la masse fluidique. La rigidité des diaphragmes de réglage (36 et 40) peut être réglée par variation de la pression à l'intérieur des chambres (38 et 40) adjacentes à ces diaphragmes.
