Abstract
A liquid-filled type vibration isolator, having a vibration isolation mechanism, formed between first and second coupling members to be mounted to a vehicle body-side member, including: a rubber-like insulator for absorbing and isolating vibrations from the vibration member; a main chamber, whose chamber walls are formed by a portion of the insulator, and which is filled with liquid; a sub-chamber, whose chamber walls are partially formed by a first diaphragm, coupled to the main chamber through a first orifice; a partitioning member for partitioning between the main chamber and the sub-chamber; a second diaphragm for partitioning between a third liquid chamber to be coupled to the main chamber through a second orifice, and a balance chamber into which negative pressure is introduced.
