ABSTRACT:
An actively controlled mount system to control vibration which permits static forces from a machine while decoupling the transmission of dynamic vibrational forces. The mount system provides a reduction of force losses from a first generating area to a second force applying area to actively control vibrations of a vibrating element. These force losses are minimized due to minimization of the mass and velocity of fluid pumped by pumping the fluid through short large cross-sectional area passageways. The device provides for channeling of the forces to the vibrating element in a uniaxial direction and constrains the application of forces in non-working directions.
