Title: The Innovative Contributions of David A. Shirley
Introduction
David A. Shirley is a notable inventor based in Pine Grove, California, with a remarkable portfolio of five patents. His work primarily focuses on advancements in shock absorber technology, which have significant implications for vehicle performance and safety.
Latest Patents
One of his latest inventions is the acceleration sensitive twin tube shock absorber. This innovative design features an inner and outer tube with an annular reservoir between them. A piston divides the inner tube into an upper and lower chamber, with valves controlling the stiffness of the shock absorber. The acceleration sensitive valve assembly allows the shock absorber to become "soft" during downward acceleration of the vehicle's wheel. This mechanism includes a port for fluid communication and an inertial mass that regulates fluid flow based on acceleration.
Another significant patent is the acceleration sensitive shock absorber, which consists of a tubular housing and a piston assembly that divides the housing into upper and lower chambers. The piston connects to the vehicle's wheel, while the housing connects to the chassis. This design allows fluid to flow between the chambers with a restricted rate during both extension and compression. A movable inertial mass opens a port during downward acceleration, enhancing fluid flow and improving performance.
Career Highlights
David has worked with prominent companies in the automotive industry, including Ricor Racing and Development, LP, and Edelbrock Corporation. His contributions to these organizations have helped advance the field of shock absorber technology.
