  • Patent number: 9010738
    Abstract: A post-formation filling type fluid filled vibration damping device wherein a first communication groove, which interconnects a plurality of through holes, is formed in a partition member that separates a pressure receiving chamber and an equilibrium chamber, the groove being formed in a surface of the partition member that opposes a flexible membrane. In addition, a second communication groove, which connects an orifice passage and at least one of the plurality of through holes, is formed in the surface of the partition member that opposes the flexible membrane.
    Type: Grant

  • Patent number: 7396003
    Abstract: A fluid-filled vibration-damping device includes an elastic body elastically connects a first mounting member and a cylindrical second mounting member bonded to opposite side thereof; a diaphragm supported by the second mounting member so that the diaphragm cooperates with the elastic body to define therebetween a fluid chamber; and a partition member supported by the second mounting member so that the partition member divides the fluid chamber into a primary fluid chamber and an auxiliary fluid chamber which are held in communication through an orifice passage defined by an orifice-defining member having a movable rubber plate disposed in its central hole. The surface of the orifice-defining member is coated at a primary-fluid-chamber-defining area by a coating rubber layer, thereby minimizing noises caused by bubbles in the fluid chamber.

  • Patent number: 7198257
    Abstract: A fluid-filled vibration damping device including: a rubber elastic body elastically connecting a first and second mounting member and partially defining a pressure-receiving chamber filled with a non-compressible fluid; a flexible layer partially defining an equilibrium chamber filled with the non-compressible fluid; an orifice passage permitting a fluid communication between the pressure-receiving chamber and equilibrium chamber; and a cushion surface situated opposite to an opening of the orifice passage to the pressure-receiving chamber in a first direction of flow of the fluid into and out of the opening, with a predetermined distance therebetween, while extending in a second direction approximately perpendicular to the first direction.

  • Patent number: 7025340
    Abstract: A fluid-filled vibration damping device includes: an elastic body connecting a first mounting member and a second mounting member; and a partition member assembled with the second mounting member to form on its opposite sides a pressure receiving chamber partially defined by the elastic body and an equilibrium chamber partially defined by a flexible layer, both being filled with non-compressible fluid. The partition member defines an orifice passage connecting the two chambers, and including a first partitioning wall portion partitioning the orifice passage from the pressure-receiving chamber, and a second partitioning wall portion of rubber partitioning the orifice passage from the equilibrium chamber. A partial reinforcing member is provided to the partition member extending across the first and second partitioning wall portions to reinforce an opening of the orifice passage to the pressure-receiving chamber.
