Title:
FLUID-FILLED VIBRATION DAMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/070850
Kind Code:
A1
Abstract:
Disclosed is a fluid-filled vibration damping device that is provided with a first liquid chamber and a second liquid chamber, inside each of which is sealed a non-compressible fluid, and to which relative pressure fluctuations are applied when vibration is input. An orifice passageway that connects the first and second liquid chambers to each other is also provided. The device is able to achieve effective vibration damping effects against multiple kinds of vibrations of differing frequencies with greater reliability and durability. Modification of the tuning frequency of the orifice passageway (68) is accomplished by adjusting how far the inner orifice member (36) enters into the outer orifice member (48) to modify the length of the orifice passageway (68).
