Latest Patents

**Dual Balance Shaft Pump Assembly.** This invention combines an engine’s dual balancing shafts with fluid pumps driven by the shafts’ distal ends. A gear train rotates the primary and secondary shafts in opposite directions, while a pump housing secured to the shaft housing encloses the pumps and retains fluid. The arrangement integrates pumping functions with the balance-shaft assembly in an automotive vehicle.

**Gas-Liquid Premixer.** This gas-turbine combustor mixer combines gaseous fuel and air in a tapered annulus, where the narrowing passage increases mixture velocity before it enters a downstream chamber. Additional air supports further mixing, while a central air passage can deliver liquid fuel independently. This separate liquid-fuel capability allows the mixer to operate with liquid injection when needed, including as a backup, and is designed to support combustion under very lean conditions.

Career Highlights

Tang’s listed company affiliations include Tesma International and Pratt & Whitney Canada. The two patents described here address distinct applications: fluid-pump integration in automotive engines and fuel-air mixing in gas-turbine combustors.

Collaborations

Tang’s listed coworkers include David R. Shulver and Dan Sarkanjac. Their names provide context for his professional network, though the supplied information does not specify their roles in either patent.

Conclusion

Wei Tang’s patent portfolio brings together practical mechanical integration for automotive engines and fuel-mixing technology for gas turbines, illustrating the range of his engineering contributions.
