CTC 008 P2 Abstract of the Disclosure An isolating mount for connecting two parts or mechanisms includes a rigid bushing surrounded by a resilient block which includes cavities on opposite sides of said bushing located along a first plane parallel to the longitudinal axis of said bushing and a passage formed between the cavities. A quantity of liquid fills the cavities and passage, providing a liquid column of predetermined inertia in the passage between the cavities for controlling forces transmitted through the bushing to provide tuning of the damping characteristics of the mount to preselected frequencies of vibration. A rigid outer body surrounds and contacts the block and exerts compressive force thereon substantially along the first plane. The bushing is connected to one of the two parts to be isolated and the outer body is connected to the other of the two parts. The cavities are closed whereby the liquid is confined within the cavities and passage so displacement of the block in response to forces acting along the first plane will result in displacement of liquid from one cavity to the other through the passage. The length and diameter of the passage are selected to provide a predetermined resonant frequency and a damping ratio of substantially 1Ø Various modifications are described for increasing the length of the passage and/or controlling its effective cross-sectional area for this purpose.
