Novel smart hydraulic pump based on PZT driver

A novel high frequency inertia check valve hydraulic pump based on piezoelectric was described. PZT Driver control the position, velocity and acceleration of the piston, while driving the piston with membrane. The inertia force helps to open and close the special check valve setting in non-inertia system, which advanced the frequency of check valve. Simulation has been done to indicate that the hydraulic pump is realizable. Many conclusions were received to direct the following researches.
