Title: Innovations of Toshimitsu Shida
Introduction
Toshimitsu Shida is a notable inventor based in Fujisawa, Japan. He has made significant contributions to the field of engineering, particularly in valve technology. With a total of seven patents to his name, Shida's work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is the Valve Rotator. This invention features a vertical movement of a valve in an engine, where a suspending member, which is engaged in the valve, moves up and down relative to a standing member on a cylinder head. A projection on the suspending member slides on inclined guide surfaces of the standing member, achieving relative rotation of the suspending member with respect to the standing member, thus allowing the valve to rotate on its axis. Another significant patent is the Poppet Valve Device. This device includes a valve stem and a valve head at one end of the stem. The valve head is equipped with a plurality of arcuate fins. Two semicylindrical cotters are pushed by a press member, driving the valve to reciprocate. As the valve moves to open a port in the valve casing, fluid flows, allowing fluid pressure to act on the fins, causing the valve to rotate slightly around its axis due to a small gap between the cotters and the valve stem.
