Fluid-filled cylindrical elastic mount having axially extending and

Abstract

A fluid-filled cylindrical elastic mount including an inner sleeve, a flange member fixed to one axial end of the inner sleeve, an outer sleeve having a cylindrical portion and a flange portion which is positioned opposite to the flange member in its axial direction, and a first and a second elastic body which are interposed between the inner and outer sleeves and between the flange member and the flange portion, respectively. These first and second elastic bodies cooperate with each other to define an annular fluid chamber which is filled with a non-compressible fluid. At least one resonance member is accommodated in the fluid chamber, and cooperates with an inner wall of the fluid chamber to define a resonance portion through which the fluid is caused to flow upon application of a vibrational load. The first elastic body includes a pair of thin-walled portions which are formed on diametrically opposite sides of the inner sleeve. Each of the thin-walled portions extends between the inner and outer sleeve, in a direction substantially parallel to the axial direction of the inner and outer sleeve, and has axially opposite ends connected to the inner and outer sleeves, respectively.
