ABSTRACT:
An engine mounting has a first armature, a second armature, a bellows interposed between the first and second armatures, and an inertia mass. The inertia mass is mounted on the bellows and vibrates independently with the first and second armatures. A partition wall formed with a passageway is disposed within the interior of the bellows and divides same into two chambers. A valve is mounted on the partition wall to open or close the passageway. The valve is responsive to a difference in pressure between the two chambers and decreases the effective area of the passageway during vibrations of the bellows with large amplitudes.
