Title:
LIQUID-SEALED VIBRATION ISOLATOR, AND ELASTIC PARTITION MEMBRANE AND CLAMPING MEMBER FOR USE THEREIN
Document Type and Number:
WIPO Patent Application WO/2005/100814
Kind Code:
A1
Abstract:
A liquid-sealed vibration isolator in which noise can be reduced greatly at the time of a high amplitude input while maintaining both the low dynamic spring characteristic at the time of a low amplitude input and the high attenuation characteristic at the time of a large amplitude input. In this liquid-sealed vibration isolator (100), since an elastic partition membrane (15) is restricted by displacement regulation ribs (17, 19) to regulate the displacement thereof, and openings (54, 56) are provided as clearance parts of the elastic partition membrane (15), noise can be reduced greatly at the time of a high amplitude input while maintaining both the low dynamic spring characteristic at the time of a low amplitude input and the high attenuation characteristic at the time of a high amplitude (intermediate amplitude) input.
