ABSTRACT:
When a unit such as a motor or other vibrating apparatus is suspended in a fixed frame, superior damping of vibration, oriented along multiple vibration axis, may be accomplished by use of the present embodiment. A supporting body, containing multiple cavities filled with a damping fluid, is located between a supporting member and a bearing member. The cavities are connected to each other by tubes. The vibration of the unit which may occur along multiple vibration axes is effectively damped by compression of the cavities and subsequent transfer of fluid through the tubes.
