FLUID-FILLED VIBRATION DAMPING DEVICE
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.
