摘要:
A liquid-sealed type vibration isolator has a resilient member disposed between the a mounting member, connected to one of a vibration-generating portion and a vibration-receiving portion, and a second mounting member, connected to the other one of the vibrator-generating portion and the vibrator-receiving portion, and the resilient member is adapted to undergo deformation during occurrence of vibrations. A pressure-receiving liquid chamber is disposed in such a manner as to be capable of expanding and shrinking by using the resilient member as a portion of a partition wall thereof. A limiting passageway allows the pressure-receiving liquid chamber and the auxiliary liquid chamber to communicate with each other. A vibrating element is supported by one of the first mounting member and the second mounting member via a resilient supporting member in such a manner as to be movable along a predetermined axis, and the vibrating element constitutes a portion of another partition wall of the pressure-receiving liquid chamber so as to be subjected to the hydraulic pressure of the pressure-receiving liquid chamber. A solenoid has a coil and a plunger adapted to move the vibrating element in one of two predetermined directions along the axis. A spring urges the vibrating element in the other one of the two predetermined directions.
