VIBRATIONPROOF DEVICE

WIPO Patent Application WO/2010/143444

A1

A liquid enclosure type vibrationproof device comprises a first attaching member (3) that is to be connected to either a vibration generating part or a vibration receiving part, a second attaching member (4) provided at the other side of the first attaching member, an elastic member (5) elastically connecting the first attaching member (3) and the second attaching member (4), and a separator (8) that divides a liquid chamber (7) inside the first attaching member (3) into an upper main liquid chamber (7A) which is partly walled by the elastic member and a lower sub-liquid chamber (7B), wherein a restriction passage (80) is formed that communicates the main liquid chamber with the sub-liquid chamber. Enclosed liquid (L) includes a first liquid (L1) as a main liquid and a second liquid (L2) as an additional liquid which is not soluble in the first liquid, wherein the vapor pressure of the second liquid (L2) is higher than the main component of the first liquid pressure at the same temperature and the specific gravity of the second liquid (L2) is smaller than that of the first liquid (L1).
