Title:
LIQUID-SEALED VIBRATION-ISOLATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/106283
Kind Code:
A1
Abstract:
A liquid-sealed vibration-isolating device capable of reducing the dependence of dynamic characteristics on the magnitude of an input amplitude, wherein an orifice (25) is formed of a route (C) having orifice flow passages (R1) and (R2). A short-circuit route (SC) smaller in cross section than the route (C) and shorter in length than the route (C) connecting two points of the route (C) to each other is formed in the route (C) of the orifice (25). Since fluid tends to pass a shorter route (namely, short-circuit route SC) when a rather small amplitude is inputted, a flow amount in the orifice (25) (route C) can be reduced to suppress fluid flow effect accordingly. As a result, the dependence of the dynamic characteristics on the input amplitude can be reduced.
