ABSTRACT:
A vibration damper including (a) an attaching member fixed to a subject member whose vibrations are damped by the vibration damping device, (b) a mass member displaceable relative to the attaching member in a vibration input direction, (c) an elastic connector elastically connecting the mass member to the attaching member and cooperating with the mass member to at least partially define a working chamber, and (d) a structure for defining a fluid passage communicating with the working chamber for changing a pressure of a fluid in the working chamber to thereby cause the mass member to be displaced relative to the attaching member in the vibration input direction.
