Title: The Innovative Mind of David Grimwade
Introduction
David Grimwade, an accomplished inventor based in Cambridge, GB, has contributed significantly to engineering advancements with his innovative inventions. With a total of two patents under his name, Grimwade's work focuses on enhancing the efficiency and safety of engine shutoff mechanisms.
Latest Patents
Grimwade's first patent is the "Stick-resistant engine over-speed shut-down valve." This invention introduces a valve body equipped with an air passageway, where a disc assembly and a valve seat assembly are integrated. The innovative design includes a disc member that rotates and moves toward the valve seat when an engine runaway condition is detected, effectively closing the valve. To prevent the disc member from sticking after closure, an anti-friction ring is included, allowing for the valve to be easily reopened.
His second patent, "Disc assembly for a valve and method of making the same," also centers on engine shutoff technology. This design features a valve body with a fluid passage that includes a pivotable disc assembly. The disc assembly can transition from an open position, permitting fluid flow, to a closed position that nearly seals the fluid passage. This configuration is notable for featuring a front disc, a rear disc, and a sealed mechanism that securely contains a spring-energized PTFE seal positioned between the two discs.
