Abstract:
1. A fluid filled type vibration damping device comprising: a first mounting member; a second mounting member; a main rubber elastic body elastically connecting the first mounting member and the second mounting member; a partition member fixedly supported on the second mounting member; a pressure-receiving chamber disposed on one side of the partition member and partially defined by the main rubber elastic body; an equilibrium chamber disposed on another side of the partition member and partially defined by a flexible film, the pressure receiving chamber and the equilibrium chamber being filled with a non-compressible fluid; an orifice passage through which the pressure receiving chamber and the equilibrium chamber communicate with one another; and a movable cover member juxtaposed against the partition member on a pressure receiving chamber side thereof to cover at least one communicating hole formed through the partition member for fluid communication between the pressure receiving chamber and the equilibrium chamber,
