摘要： A liquid-filled vibration isolator A has a first orifice channel P1 providing communication between a pressure receiving chamber f1 and a balancing chamber f2. One of the pressure receiving chamber f1 and the balancing chamber f2 is communicated via a second orifice channel P2 with an intermediate liquid chamber f3. The second orifice channel P2 has a shorter distance or a larger cross-sectional area than the first orifice channel P1. An elastic film member, such as a membrane 42, separates the intermediate liquid chamber f3 and the other of the pressure receiving chamber f1 and the balancing chamber f2 from each other. A communicating hole 42a of a predetermined size is formed in the elastic film member. An imaginary orifice channel combined from the two orifice channels P1 and P2 provides a high damping effect on input vibration of relatively low frequency. As the vibration frequency increases, a gradual transition is made to the damping characteristic of the second orifice channel P2 only.
