Abstract
A fluid-filled vibration damping device including: a first mounting member; a second mounting member; a main rubber elastic body elastically connecting the first and second mounting members; a pressure-receiving chamber whose wall is partially constituted by the main rubber elastic body; an equilibrium chamber whose wall is partially constituted by a flexible film, the pressure-receiving chamber and equilibrium chamber being filled with a non-compressible fluid; and an orifice passage which connects the pressure-receiving chamber and the equilibrium chamber to each other. A turbulence generating part is formed in a middle portion of the orifice passage in a length direction causing turbulence to be generated depending on a flow rate of a flowing fluid.
