Fluid-filled elastic mount having orifice passages tuned to damp input vibrations in respective different frequency ranges

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