ABSTRACT:
A fluid filled type vibration damping device includes: a main rubber elastic body elastically connecting first and second mounting members; a partition member supported by the second mounting member; a pressure-receiving chamber partially defined by the elastic body and having a non-compressible fluid sealed therein; an equilibrium chamber partially defined by a flexible film and having the non-compressible fluid therein. The chambers are formed to either side of the partition member and an orifice passage permits a fluid communication between the two chambers. A short-circuit passage is formed so that the pressure-receiving and equilibrium chambers are able to be short-circuited through the short-circuit passage. A valve is used for switching the short-circuit passage, and a metal spring is used for holding the valve in a closed state at a predetermined initial level of elastic deformation.
