Abstract
A vibration isolation system includes a vibration isolator configured to flow a fluid. A fluid pumping system is connected to the vibration isolator. The fluid pumping system includes a fluid flow pathway configured to flow the fluid to the vibration isolator. The fluid pumping system includes a piston assembly positioned in the fluid flow pathway. The piston assembly includes a first piston and a second piston configured to displace the fluid in opposite directions through the fluid flow pathway. The vibration isolation system includes a fluid flow augmentation system, which includes an eccentric member positioned between the first piston and the second piston. The fluid flow augmentation system is configured to control a flow of the fluid to the vibration isolator through the fluid flow pathway by controlling a displacement of the first piston and the second piston through at least a partial rotation of the eccentric member.
