<p><P>PROBLEM TO BE SOLVED: To provide a fluid-filled type vibration control device of a new structure effectively exerting a required vibration control effect by achieving a larger tuning flexibility and broadening of the vibration control characteristics. <P>SOLUTION: A bag-like rubber 72 of an inverted cup-shape including a cylindrical peripheral wall 74 and an upper bottom 76 has an opening peripheral edge fixed to a partition member 44 so that the bag-like rubber is arranged to project from the central part of the partition member 44 toward a first mounting member 12 and, with approaching displacement of the first mounting member 12 and a second mounting member 14 by the input of a load, the upper bottom 76 is pressed and elastically deformed by the second mounting member 12. An opening on a pressure receiving chamber 60 side of an orifice passage 70 is provided while avoiding the bag-like rubber 72 to an outer peripheral side and a vibration isolation control part 89 is provided in the opening portion of the bag-like rubber 72 at the partition member 44 for determining a communication state between the internal area 88 of the bag-like rubber 72 and a balance chamber 62. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
