Vibration-damping device having independent mass member
First Claim
1. A vibration-damping device for elastically connecting two members of a vibration system in a vibration damping fashion, said vibration-damping device comprising:
- a first mounting member attachable to one of the two members of the vibration system;
a second mounting member disposed away from said first mounting member and attachable to an other one of the two members of the vibration system;
an elastic body disposed between and elastically connecting said first and second mounting members, said elastic body including a connecting portion that extends between said first and second mounting members and has a hollow housing portion formed therein; and
an independent mass member accommodated in said housing portion such that said independent mass member is independently displaceable relative to said housing portion without being bonded to said housing portion, and is brought into direct and elastic impact against said housing portion.

Abstract
Disclosed is a vibration-damping device comprising: a first and a second mounting member disposed in mutually spaced apart relationship with each other and attachable to two members of a vibration system, respectively; and an elastic body disposed between and elastically connecting the first and second mounting members and including a connecting portion adapted to primarily connect the first and second mounting members. The connecting portion has a hollow housing portion in which an independent mass member is accommodated such that the independent mass member is independently displaceable relative to the housing portion without being bonded to the housing portion, and is brought into direct and elastic impact against the housing portion.

11. A vibration-damping device according to claim 11, further comprising:
- a partition structure adapted to fluid-tightly divide said fluid chamber into a pressure receiving chamber partially defined by said elastic body whose pressure is variable due to an elastic deformation of said elastic body, and an equilibrium chamber partially defined by a flexible diaphragm whose volume is variable due to an elastic displacement of said flexible diaphragm; and
an orifice passage for fluid communication between said pressure receiving chamber and said equilibrium chamber, said vibration damping device exhibiting a vibration damping effect on the basis of resonance of said fluid flowing through said orifice passage.
- a partition structure adapted to fluid-tightly divide said fluid chamber into a pressure receiving chamber partially defined by said elastic body whose pressure is variable due to an elastic deformation of said elastic body, and an equilibrium chamber partially defined by a flexible diaphragm whose volume is variable due to an elastic displacement of said flexible diaphragm; and
