ABSTRACT:
A fluid-filled vibration damping device including an elastic body connecting two mutually spaced-apart mounting members and partially defining a primary fluid chamber filled with a non-compressible fluid a pressure of which changes upon application of a vibrational load between the mounting members, and a movable member which partially defines an auxiliary fluid chamber filled with the non-compressible fluid and communicating with the primary fluid chamber through an orifice. The movable member is oscillated to cause a periodic pressure change of the fluid in the auxiliary fluid chamber, by a periodic change of an air pressure which is applied to a working air chamber formed on one of opposite sides of the movable member which is remote from the auxiliary fluid chamber.
