IPC: F16F13/08
Filed: 1992-08-28
Abstract: PURPOSE:To provide a high-performance liquid-filled vibration control device suitably usable even in a high temperature atmosphere. CONSTITUTION:A liquid-filled space closed by a rubber elastic body 3 is partitioned by a partition plaste 5 with a throttle passage 51 formed so as to form a pair of liquid chambers A, B. Coil springs 6 are provided between the partition plate 5 and an upper plate 1, and an agitation plate extended inward and outward in the liquid chamber is provided at the intermediate position of the coil spring 6. The static load of a vibrator is supported by the coil springs 6 so as to be hardly applied to the rubber elastic body 3. The rubber elastic body 3 is therefore prevented from being deformed in the distorted state by static load and also prevented from being deteriorated even in a high temperature atmosphere. The rise of a spring constant caused by the resonance of the coil spring in a high frequency vibration region is suppressed by liquid resonance generated by the agitation plate moving rapidly in the vertical direction so as to absorb high frequency vibration desirably.
