Title:
LIQUID SEALED-IN TYPE VIBRATION DAMPER
Document Type and Number:
WIPO Patent Application WO/2002/081944
Kind Code:
A1
Abstract:
A liquid sealed-in type vibration damper comprising an orifice member (26) for a partition (7), a partition plate member (27) crimped to the vibration damper main body under the orifice member (26), a rubber-like elastic membrane (28) disposed in an annular space defined between these members (26, 27), the base (40) of the rubber-like elastic membrane being fixed to one member, either the orifice member (26) or the partition plate member (27), the front end side being an open end (34), the open end (34) being slidably pressed against the other member, thus providing a cantilever type slide membrane construction, whereby the amplitude dependency is reduced and the middle and high frequency dynamic spring constant is reduced over a wide range and noise can be reduced.
