Abstract
A hydrostatic anti-vibration system includes a main tank provided on a construction to be suppressed from vibrating and having a main tank body of substantially flat rectangular configuration. Hollow vertical extensions extend upwardly from peripheral edge portions of the main tank body and are filled with a working liquid at a predetermined level with upper air chambers maintained thereabove. Ducts communicate the upper air chambers of the hollow vertical extensions. Intermediate tank portions are disposed at the intermediate portions of respective ducts and contain a vibration suppressing liquid. A pivotal plate is disposed in each of the intermediate tank portions to separate the interior space of the intermediate tank portion into a pair of chambers respectively connected to corresponding portions of the duct. The plate pivots in response to flow pressure of the vibration suppressing liquid. A damping mechanism provides a resistance against displacement of the pivotal plate.
