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.
