Patent number: 9394964Abstract: A fluid-filled vibration damping device including a second orifice passage and a third orifice passage tuned to a lower frequency than the second orifice passage, and an actuator including an output portion facing openings of the second and third orifice passages on a side of an equilibrium chamber via a flexible film. The flexible film obstructs the openings of the second and third orifice passages when the output portion comes into contact against a partition member so that the third orifice passage is blocked while the second orifice passage is substantially placed in communication owing to a center recess of the output portion permitting deformation of the flexible film. Meanwhile, the flexible film is separated from the openings of the second and third orifice passages when the output portion is separated from the partition member so that the two orifice passages are placed in communication.Type: GrantFiled: October 22, 2013Date of Patent: July 19, 2016Assignee: SUMITOMO RIKO COMPANY LIMITEDInventors: Takayoshi Yasuda, Hiroyuki Ichikawa, Akio Saiki
