US Patent Issued on Oct. 27 for "Piezoelectric hydraulic piston pump" (New York Inventor)

ALEXANDRIA, Va., Oct. 27 -- United States Patent no. 12,774,704, issued on Oct. 27.

"Piezoelectric hydraulic piston pump" was invented by Lucas Marrero (New York).

According to the abstract* released by the U.S. Patent & Trademark Office: "The embodied invention is a piezoelectric hydraulic piston pump. There is a single inlet and a single outlet leading into a fluid chamber. The piston separates the chamber housing from the piezoelectric actuator from the fluid chamber. The controls are simplified to take full advantage of the precision movement of the invention. A pump controller sends a signal to a piezo driver which causes a piston to move which creates pressure and flow. The embodied piezoelectric hydraulic pump requires a high-force...
