摘要： A fluid filled vibration damping device including: an elastic body elastically connecting a first and a second mounting member and partially defining a pressure receiving chamber filled with a non-compressible fluid; a flexible diaphragm partially defining an equilibrium chamber filled with the non-compressible fluid and connected to the pressure-receiving chamber via an orifice passage. The first mounting member includes an elastic-body-side central member bonded to the elastic body central portion, and a rubber-layer-side central member bonded to the flexible rubber layer central portion, both mutually superposed on and fastened together by a connecting bolt. A fitting recess and projection are formed at an interface between two members, and a mounting projection projecting outward on an opposite side from the interface. The connecting bolt is off-centered from a center of the two members by a give distance.

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.

The movable rubber plate is moved owing to the pressure difference between the two chambers. The movable rubber plate comprises the movable rubber plate formed of a generally disk shaped rubber elastic body having formed thereon in alternating fashion concave grooves and convex ribs each extending in a circumferential direction about a same center axis, the convex ribs have tapered cross section gradually narrowing in width towards an distal end thereof, and the concave grooves and convex ribs are disposed at the same locations in a diametrical direction on either face of the movable rubber plate so that the thickness of the movable rubber plate is varied in the circumferential direction.
