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 type active vibration damping device including: a pressure-receiving chamber; an equilibrium chamber; an orifice passage permitting fluid flow between the two chambers; an oscillation member oscillated by an electromagnetic actuator; an intermediate chamber; and a pressure transmission passage through which pressure fluctuations produced in the intermediate chamber is applied to the pressure-receiving chamber. The intermediate chamber is provided independently of the equilibrium chamber. The pressure transmission passage comprises a filter orifice tuned to higher frequency than the orifice passage. A movable plate is provided for limiting an amount of fluid flow through the filter orifice. A leak hole is formed for continuously interconnecting the intermediate chamber and the pressure-receiving chamber, and a liquid column resonance frequency of the leak hole is set to not more than half of that of the filter orifice.

摘要： A fluid-filled type vibration damping device including a base component and a tubular mating component. The tubular mating component is externally fitted onto the base component by means of a diameter-constricting caulking with a sealing rubber clasped therebetween so as to constitute a mate-fastened portion. The tubular mating component extends axially outward beyond a sealed section of the mate-fastened portion so as to provide a caulking tube portion. A diametrical position of the tubular mating component at the sealed section is determined by contact of the caulking tube portion against an outside peripheral face of a positioning projection provided on the base component so as to define a diametrical positioning portion. The caulking tube portion is constricted in diameter and held in engagement with an axial edge portion of the positioning projection so as to form an axial positioning portion.
