Abstract:
A fluid-filled vibration damping device comprising:a first mounting member and a second mounting member, which are disposed in mutually spaced-apart relationship with each other; an elastic body elastically connecting said first and second mounting member and partially defining a primary fluid chamber filled with a non-compressible fluid whose pressure varies due to an elastic deformation upon application of a vibrational load between said first and second mounting members; a movable rubber plate partially defining said primary fluid chamber such that a peripheral portion of said movable rubber plate is bonded to and fluid-tightly supported by a rigid wall portion of said primary fluid chamber so that fluid pressure variation induced in said primary fluid chamber is regulated or controlled by displacement of said movable rubber plate owing to its elastic deformation, said movable rubber plate having an engaging portion; an engaging member fixedly supported by said second mounting member such that said engaging member is disposed on one of, opposite sides of said movable rubber plate with a spacing therebetween to be remote from said primary fluid chamber, and is engaged with said engaging portion of said movable rubber plate so that an amount of displacement of said movable rubber plate is restricted at least in a direction toward an interior of said primary fluid chamber.
