Title: Chungnin C. Wong and His Miniature Electrically Operated Diaphragm Valve.

Introduction

Chungnin C. Wong is an inventor associated with Albuquerque, New Mexico, and Sandia Corporation. His work includes a patent for a miniature electrically operated diaphragm valve designed to control fluid flow in a compact, energy-efficient device.

Latest Patents

Wong’s listed patent is “Miniature Electrically Operated Diaphragm Valve.” The invention describes a valve with a housing, a beam, a diaphragm, electromagnetic actuation, and two fluid ports. The beam moves the diaphragm to open or seal a port, controlling whether fluid can pass through the housing.

The design aims to withstand significant pressure while remaining inexpensive to produce. It can also use latching mechanisms, such as permanent magnets, to hold the valve open or closed without continuous electrical power. The patent record lists 1 patent for Wong.

Career Highlights

Wong’s patented valve combines electromagnetic actuation with a diaphragm-based sealing mechanism. The design allows the beam to move in opposing directions through passive means, reversed electromagnetic polarity, or a second electromagnetic source. Different embodiments can accommodate variations in the latching mechanism, electromagnetic source, number of ports, and diaphragm design.

Collaborations

Wong is associated with Sandia Corporation. His listed coworkers include Gregory Charles Frye-Mason and Barry Louis Spletzer.

Conclusion

Chungnin C. Wong’s patented valve presents a compact approach to pressure-resistant fluid control, with a latching design that can reduce the need for continuous electrical power.
