<p>A vibration control device, wherein a controller operates selector valves of N in quantity sequentially connected to a balance room selectively one by one in synchronism with input vibration from a vibration generating part to lead negative pressure and atmospheric pressure alternately into the balance room through the selector valves, whereby an internal pressure (barometric pressure) in the balance room is varied in synchronism with the input vibration and the inner volume of the balance room is varied to absorb liquid pressure variation (up) in a pressure receiving liquid chamber caused when vibration is inputted by the volumetric change of the balance room. Since the selector valves of N in quantity are connected to the balance room, a frequency for operating the selector valves can be increased by approx. N times as compared with that when the number of the selector valves is one.</p> |
