Abstract:
1. A liquid-filled vibration damping device comprising: a liquid-filled space which sealingly contains liquid; a partition member which partitions the liquid-filled space into a plurality of chambers communicating with each other through an orifice; a molded vulcanized rubber member which defines at least a part of the liquid-filled space; and a retention member which retains the molded vulcanized rubber member; the device being adapted to damp vibrations transmitted to the molded vulcanized rubber member by resilient deformation of the molded vulcanized rubber member and flow of the liquid between the chambers; wherein the liquid comprises a polar organic solvent as a major component, and not less than 0.2 cm whereby the device alleviates a pressure change occurring in the liquid-filled space due to the resilient deformation of the molded vulcanized rubber member by gasification and liquefaction of the dissolved gas.
