PURPOSE:To provide a liquid-filled vibration control device of high performance 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 plate 5 with a throttle passage 51 formed therein so as to form a pair of liquid chambers A, B. A coil spring 6 is provided between the partition plate 5 and an upper plate 1, and the lower end of the coil spring 6 is fixed to a receiving member 7 sliding on the recessed spherical face 5a of the partition plate 5. Since the static load of a vibrator is suppoted by the coil spring so as to be hardly applied to the rubber elastic body 3, the rubber elastic body 3 is not deformed in the distorted state by the static load nor degraded even in a high temperature atmosphere because of the use of heat resisting rubber. Also, even when the attitude of the vibrator changes to cause the change of the opposed attitude of the upper plate 1 to the partition plate 5, the coil spring 6 is rotated around a fixed point C at one end without changing its attitude to the upper plate 1. Vibration is thereby always inputted to the coil spring 6 from the axial direction to avoid the lowering of its durability. |
