Abstract
A fluid filled type vibration-damping device including: an elastic body connecting a first and second mounting member and sealing off one opening of the second mounting member; a flexible film fluid-tightly sealing off an another opening of the second mounting member; a partition member firmly fitted into the second mounting member thereby forming a pressure-receiving chamber partially defined by the rubber elastic body and an equilibrium chamber partially defined by the flexible film, which communicate together via an orifice passage; a short circuit passage is formed to connect the two chambers, and a valve body placing the short circuit passage in a communicating state on a basis of elastic deformation of the elastic body when an excessive pressure differential arises between the two chambers.
