Abstract
A fluid-filled elastic mount including an elastic body elastically connecting first and second mounting members and partially defining a pressure-receiving chamber filled with a fluid, a flexible diaphragm partially defining an equilibrium chamber filled with the fluid and displaceable to permit a volume change of the equilibrium chamber, a first orifice passage for fluid communication between the two chambers, a movable member disposed between the two chambers and displaceable or deformable to permit relative volume changes of the two chambers, a second and a third orifice passage formed between the movable member and one of the two chambers for permitting the fluid to flow therethrough based on displacement or deformation of the movable member. The second orifice passage is tuned to a frequency range higher than that of the first orifice passage while the third orifice passage is tuned to a frequency range higher than that of the second orifice passage, and a control device for permitting or inhibiting fluid flows through the third orifice passage.
