Abstract
A fluid-filled damping device wherein a center shaft member and an outer cylindrical member are elastically connected by first and second elastic end walls and an elastic intermediate wall interposed between the end walls. The first elastic end wall has two recesses opposed to each other in a first diametric direction of the center shaft member, and cooperates with the elastic intermediate wall and the outer cylindrical member to define a first fluid chamber. The intermediate wall cooperates with the second elastic end wall and two partition blocks to define a first and a second pocket which are opposed to each other in the first diametric direction. The two partition blocks are interposed between the intermediate and second end walls and opposed to each other in a second diametric direction perpendicular to the first diametric direction. The two pockets are closed by the outer cylindrical member to provide a second and a third fluid chambers communicating with the first fluid chamber.
