Fluid-filled mounting device

Abstract

Abstract PURPOSE:To provide a fluid-sealed mounting device having a new structure and the improved vibration-proof characteristic for input vibrations in the medium/high-frequency areas. CONSTITUTION:A fluid-sealed mounting device is connected with the first fitting metal 10 and the second fitting metal 12 via a rubber elastic body 14, and it is formed with a pressure receiving chamber 38 and an equilibrium chamber 40 communicated via the first orifice passage 68 on both sides across a partition member 36. A through hole 58 extended astride the pressure receiving chamber 38 and the equilibrium chamber 40 is provided on the partition member 36. The first rubber elastic plate 54 and the second rubber elastic plate 56 having larger rigidity against the volume change than that of the first rubber elastic plate 54 are arranged at a preset distance in the through hole 58, and an intermediate chamber 60 communicated with the equilibrium chamber 40 via the second orifice passage 72 having a cross sectional area/length ratio larger than that of the first orifice passage 68 is formed between both rubber elastic plates 54, 56.
