Title: Fluid amplifiers and vibration damping and isolation systems

Abstract: Fluid amplifiers and vibration damping and isolation systems are provided. A fluid amplifier includes a housing assembly, a piezo-electric element, two amplification stages, and a rod. The piezo-electric element is disposed within the housing assembly and is capable of being energized to lengthen axially to provide an input stroke at an initial magnitude. The first amplification stage is disposed within the housing assembly adjacent to the piezo-electric element and is adapted to amplify the input stroke from the piezo-electric element to a first magnitude. The second amplification stage is disposed in series with the first amplification stage and is adapted to increase the input stroke from the first magnitude to a second magnitude that is greater than the first magnitude to yield an amplified input stroke. The rod extends through the second amplification stage and is coupled thereto to transmit the amplified input stroke having the second magnitude.
