Fluid-filled elastic mounting structure

摘要

A fluid-filled elastic mounting structure includes an elastic member, hat-shaped outer and inner partition members superimposed on each other with their cup-shaped portions open on the same side and cooperating with the elastic member to define an operating chamber, and a flexible closure member cooperating with the outer and inner partition members to define an equilibrium chamber. The operating and equilibrium chambers are filled with a fluid and communicate with each other through an annular space which is defined by the cylindrical walls of the outer and inner partition members. The outer and inner partition members cooperate to define a flat space between their bottom walls. The flat space communicates with the operating and equilibrium chambers so that a movable member accommodated in the flat space is movable by a force applied to the fluid in the operating chamber, or a pressure in the operating chamber acts on the fluid in the equilibrium chamber through movements of the movable member within the flat space.
