Title: Andrew Plummer and the Piezo-Electric Fluid Pump.
Introduction
Andrew Plummer is an inventor based in Bath, Great Britain. His patent work includes a piezo-electric fluid pump, an invention designed to improve the pressure and flow capabilities of piezo-electric pumping systems.
Latest Patents
Plummer’s listed patent is titled “Piezo-electric fluid pump.” The invention combines a main housing and fluid reservoir with a movable piston head, a piezo-electric stack, and a bias mechanism that couples the piston head to the stack while keeping the stack under compression. An outlet plate and the piston head form a pumping chamber, while inlet and outlet disc valves control one-way fluid flow into and out of that chamber. According to the patent description, pre-loading the piezo-electric stack in compression and using an inlet disc valve can substantially improve pressure and flow performance compared with other piezo-electric pumps. Plummer is credited with 1 patent.
Career Highlights
Plummer is associated with Safran Landing Systems UK Ltd. His patented pump design reflects work on fluid-handling technology and the performance of piezo-electric systems.
