Abstract
A fluid-filled vibration damping device having an elastic body connecting two mutually spaced-apart mounting members, a fluid chamber filled with a non-compressible fluid, and a movable member which partially defines the fluid chamber and which is oscillated to control a pressure of the fluid in the fluid chamber, for regulating damping characteristics of the device. The movable member partially defines a working air-chamber on one of opposite sides thereof which is remote form the fluid chamber, and is oscillated by a periodic change of an air pressure which is applied to the working air-chamber. A restoring member is disposed on at least one of opposite sides of the movable member for elastically supporting the movable member, so that an elastic force of the restoring member acts on the movable member to restore the movable member to an original position thereof during oscillation thereof.
