摘要： A fluid-filled type vibration-damping device having an elastic rubber film partially defining a primary fluid chamber at one surface and partially defining a pressure action chamber. The pressure action chamber varies its pressure under control so that the elastic rubber film changes its elasticity to change damping characteristics of the device. To give sufficient recovery force for the elastic rubber film, the elastic rubber film includes a plurality of thick reinforcing ribs circumferentially spaced apart from one another and extending in a radial direction from an outside peripheral edge over a length not reaching a center so that areas situated between pairs of adjacent reinforcing ribs constitutes thin portions formed by a thin rubber elastic body, while the center portion of the elastic rubber film situated between distal ends constitutes a bowed center portion thinner than the reinforcing ribs and convex towards the pressure action chamber.

摘要： A fluid filled active vibration damping device wherein a first and a second mounting member are coupled by a rubber elastic body, thereby forming a pressure receiving chamber defined at one part by the rubber elastic body, with a non-compressible fluid sealed therein, and at another part by an excitation plate capable of displacement. An electromagnetic actuating assembly are disposed on the pressure receiving chamber side with the excitation plate therebetween. The excitation plate is oscillated by application of electronical current to a coil member in the electromagnetic actuating assembly. The output member projects out towards the excitation plate from the electromagnetic actuating assembly, and a permanent magnet is disposed in the output member and/or the excitation plate in order to couple the output member and the excitation plate through magnetic force.

摘要： A fluid filled type vibration damping device includes a fluid chamber divided by a partition member into a pressure-receiving chamber and an equilibrium chamber. The partition member has a first and a second member axially superposed together. A locking projection is formed on one of the first member or the second member and a locking hole is formed on an other, with the locking projection being inserted through the locking hole to effect locking so as to constitute a locking mechanism for holding the first and second member in a superposed state. Outer circumferential faces of the first member and the second member held in the superposed state by the locking mechanism are fastened fitting into a second mounting member via a seal rubber layer, and the first or second member having the locking hole includes a cover portion that covers an opening of the locking hole from a side thereof to which the locking projection projects.
