摘要： A vibration damping device wherein a stopper rubber disposed between opposing faces of a first mounting member and the retainer member so as to project from one of the opposing faces to the other. When the first and second mounting members undergoes relative displacement axially towards each other, a shock produced at a time when an abutting face of the first mounting member comes into contact with the open end face, i.e., an abutting face of the retainer member absorbed by the stopper rubber coming into contact with the other one of the opposing faces until the first mounting member comes into contact with the open end face of the retainer member. A receiving space is disposed between the opposing faces of the first mounting member and the retainer member so that the stopper rubber is accommodated in an elastically compressive-deformed state within the receiving space when the abutting faces contact together.

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 vibration damping device includes: a main rubber elastic body elastically connecting first and second mounting members; a partition member supported by the second mounting member; a pressure-receiving chamber partially defined by the elastic body and having a non-compressible fluid sealed therein; an equilibrium chamber partially defined by a flexible film and having the non-compressible fluid therein. The chambers are formed to either side of the partition member and an orifice passage permits a fluid communication between the two chambers. A short-circuit passage is formed so that the pressure-receiving and equilibrium chambers are able to be short-circuited through the short-circuit passage. A valve is used for switching the short-circuit passage, and a metal spring is used for holding the valve in a closed state at a predetermined initial level of elastic deformation.

摘要： Disclosed is a pneumatically operated fluid-filled active vibration-damping device including: a primary fluid chamber partially defined by an elastic body and filled with a non-compressible fluid; a movable member being elastically displaceable and partially defining the primary fluid chamber its one side; a working air chamber disposed on the other side of the movable member; and an air reservoir directly extending from the working air chamber and fluid-tightly closed at its protruding end portion. A fluid pressure variation in the primary fluid chamber is induced by an elastic deformation of the elastic body while being actively controlled by transmitting an air pressure variation applied to the working air chamber from an external area to the primary fluid chamber via the movable member. A vibration-damping apparatus using the vibration-damping device is also disclosed.
