<P>PROBLEM TO BE SOLVED: To provide a fluid-filled vibration damping device with a novel structure, capable of obtaining a sufficiently large damping effect while avoiding the occurrence of cavitation in a pressure receiving chamber. <P>SOLUTION: A connection flow path 50 having a cross-sectional area larger than that of an orifice passage 72 and extended between a pressure receiving chamber 42 and a balance chamber 44 is formed on a partitioning member 40, and an elastic tubular body 62 is formed which is protruded from one side to the another wide of the partitioning member 40 side and a first attaching member 12 side in an opening part of the connection flow path 50 to the pressure receiving chamber 42. An end opening 68 of the elastic tubular body 62 is pressed to an inner surface of the pressure receiving chamber 42 under a mounting state with a static support load applied so that the connection flow path 50 is brought into a blocking state, and meanwhile as a tensile load is input, the end opening 68 of the elastic tubular body 62 is separated from the inner surface of the pressure receiving chamber 42 to bring the connection flow path 50 into a communication state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
