| Summary: | The disclosure of Japanese Patent Application No. 2001-320233 filed on Oct. 18, 2001 including the specification, drawings and abstract is incorporated herein by reference in its entirety.
Disclosed is a fluid-filled cylindrical vibration damping device including an elastic body interposed between an inner and outer sleeves for elastically connecting these sleeves with each other. A plurality of fluid chambers filled with a non-compressible fluid are partially defined by the elastic body so that a pressure of the fluid in the plurality of fluid chambers vary upon application of a vibrational load to the vibration damping device. A first orifice passage permitting a fluid communication between the fluid chambers is at least partially defined by an elastic member adapted to be subjected to shear deformation due to a fluid pressure acting on the first orifice passage so that a cross sectional area of the first orifice passage increases according to an increase of the pressure of the fluid acting on the first orifice passage owing to the shear deformation of the elastic member. |
