摘要:
A fluid filled cylindrical vibration damping device having a main rubber elastic body elastically connecting an inner shaft member and an intermediate cylindrical member, wherein base wall portions of either of a pair of pocket portions are constituted by the main rubber elastic body to actively rise opposing positive/negative pressure fluctuations in a pair of fluid chambers at times of vibration input across the inner shaft member and the outer cylindrical member; a low-frequency orifice passage and a high-frequency orifice passage are provided; and the high-frequency orifice passage is provided in an aperture section thereof leading to at least one of the pair of fluid chambers with a moveable film adapted to limit fluid flow through the high-frequency orifice passage on the basis of displacement and/or deformation thereof.
