Title:
LIQUID-SEALED VIBRATION-ISOLATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/119645
Kind Code:
A1
Abstract:
A partition body (40) for separating a first liquid chamber (36A) and a second liquid chamber (36B) from each other comprises an annular, orifice forming member (44), an elastic wall (46) for closing the opening defined by the inner peripheral surface (44A) of the orifice forming member, and a pair of partition plates (48, 50) for sandwiching the elastic wall in the axis direction (X) thereof. A through-hole (80) which penetrates through in the axis direction (X) is formed in either the partition plate (48) and/or the partition plate (50) so as to be located on the outer side (Ko) of a joining section (56) in the radial direction. When vibration having small amplitude is inputted, a liquid flow is generated within the through-hole (80) in the partition plate, and this causes the through-hole (80) to act as a high-frequency orifice path.
