ABSTRACT:
A vibration isolation apparatus having a shaft with an axis therethrough. The shaft has a first and second end. A piston having an axial bore is coaxially positioned with the shaft to provide a damper by forming a damping path between the piston and the shaft. A flange extends radially from the piston for coupling the apparatus to a load. A first extension is coupled to and extends radially from the first end of the shaft and a second extension is coupled to and extends radially from the second end of the shaft. Secondary bellows extending from and secondary fluid paths extending through the first and second extensions provide a first volumetric stiffness in series with the damper. Primary bellows connect the flange to the first and second extensions and are coaxial with the shaft to provide a second volumetric stiffness parallel with the damper and the first volumetric stiffness.
