摘要： A fluid-filled vibration damping device including: a pressure-receiving chamber and an equilibrium chamber disposed on either side of a partition plate, while being connected through a first orifice passage; a moveable film arranged to either a pressure-receiving chamber side or an equilibrium chamber side of the partition plate while being spaced away therefrom to define therebetween an intermediate chamber; a second orifice passage connecting the intermediate chamber and one of the pressure-receiving and the equilibrium chambers while being tuned to higher frequency than the first orifice passage; and a flow straightening plate arranged in opposition to the moveable film at least at one of the intermediate chamber side and an opposite side thereof, the flow straightening plate having a plurality of flow straightening apertures opening towards the moveable film and furnished with a flow limiting member.

摘要： A fluid-filled type vibration damping device wherein a low-frequency orifice passage and at least one high-frequency orifice passage are formed in a partition member, which is supported by a second mounting member member; a valve body is disposed at least at one opening of the high-frequency orifice passage and is provided with a spring member that in a nonloaded state positions the valve body away from the opening of the high-frequency orifice passage to hold the high-frequency orifice passage in an open state; and, at times of vibration input, the valve body is adapted to block the high-frequency orifice passage in opposition to a holding force of the spring member.
