Abstract:
A fluid-filled type vibration damping device wherein a second mounting member is secured to a vehicle body; an opening of the second mounting member is closed off to define a pressure-receiving chamber a flexible film is arranged covering an outside of a main rubber elastic body to define an equilibrium chamber; a low-frequency orifice passage and a high-frequency orifice passage connect the pressure-receiving chamber and the equilibrium chamber a first moveable member is disposed on a fluid channel through the high-frequency orifice passage; the first moveable member being supported by a first support member that is linked to the second mounting member via the main rubber elastic body; and a fluid channel through the low-frequency orifice passage is situated away from the placement location of the first moveable member.
