摘要： A vibration damping device including: a pressure-receiving chamber and an equilibrium chamber connected by a first orifice passage; a movable member disposed within the pressure-receiving chamber, to form a primary fluid chamber partly defined by a rubber elastic body, and an auxiliary fluid chamber partly defined by an oscillating plate; and a second orifice passage connecting the auxiliary fluid chamber to the equilibrium chamber. A through-hole is formed in a partition member that partitions the primary fluid chamber and the auxiliary fluid chamber, the oscillating plate is housed within the through-hole with a gap provided therebetween whereby the oscillating plate is displaceable in an axial direction within the through-hole. A stopper abutted by the oscillating plate during displacement to one axial side is provided, with the gap becoming closed off when the oscillating plate is in a state of abutment against the stopper.

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.
