ABSTRACT:
A liquid-sealing type vibration isolating apparatus including a first coupling member attached to a vibrator; a second coupling member attached to a member in a vehicle body; an insulator interposed between the coupling members, for absorbing and isolating vibration from the vibrator; a vibration isolating mechanism composed of a main chamber having a chamber wall formed by a portion of the insulator, and charged therein with liquid, an auxiliary chamber communicated with the main chamber through an orifice and having a chamber wall a portion of which is formed by a first diaphragm, an air chamber partitioned from the auxiliary chamber across the first diaphragm, and an equilibrium chamber partitioned from the auxiliary chamber across a second diaphragm; a selector for carrying out change-over operation so as to introduce negative pressure or the atmospheric pressure into the equilibrium chamber in the vibration isolating mechanism control for controlling the change-over operation of the selector, a negative pressure tank provided between a negative pressure source and the selector, and a check valve formed between the negative pressure tank and the negative pressure source, for allowing introduction of only negative pressure, and a solenoid mechanism for driving the selector.
