摘要： A fluid-filled vibration damping device including: a primary fluid chamber which gives rise to internal pressure fluctuations based on deformation of a main rubber elastic body at times of vibration input; an auxiliary fluid chamber which gives rise to pressure differentials relative to the primary fluid chamber at times of vibration input; an orifice passage which permits a non-compressible sealed fluid filling the primary fluid chamber and the auxiliary fluid chamber to flow between the two fluid chambers; and an insoluble powder mixed in the sealed fluid filling the primary fluid chamber which provides a bubble nucleus and accelerates dispersed generation of bubbles when pressure within the primary fluid chamber is decreased.

摘要： An excellent liquid-filled vibration damping device is provided, which is capable of effectively suppressing cavitation, which may otherwise cause abnormal noises, without impairing a vibration damping effect. The inventive liquid-filled vibration damping device includes a liquid-filled space partitioned into a primary liquid chamber and a secondary liquid chamber 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 first retention member and a second retention member retaining the molded vulcanized rubber member. Liquid (P) to be sealingly contained in the liquid-filled space comprises a polar organic solvent as a major component, and not less than 0.2 cm3 of a gas per 1 cm3 of the liquid as measured at an ordinary temperature at an atmospheric pressure is dissolved in the liquid.

摘要： A fluid-filled vibration damping device including an elastic buffer body supported by a partition member and arranged in a housing space such that at least one of wall inner surfaces of the housing space on sides of a pressure-receiving chamber and an equilibrium chamber is covered by the elastic buffer body. Windows are formed to penetrate the elastic buffer body at portions corresponding to communication holes formed in walls of the housing space so that the communication holes are narrowed by the windows of the elastic buffer body, and a ratio (a/l) of an opening area (a) of the windows to a penetration length (l) thereof is made smaller than a ratio (A/L) of an opening area (A) of the communication holes to a penetration length (L) thereof.
