Title: Kei Ueda and His Engine Valve Operating System Patent.
Introduction
Kei Ueda is an inventor associated with Wako, Japan, and Honda Motor Co., Ltd. His patent work includes an invention designed to improve the operation of valves in multicylinder engines.
Latest Patents
Ueda is credited with 1 patent: “Valve Operating System for Multicylinder Engine.” The system uses a camshaft-mounted cam to operate pairs of rocker arms, which open and close the valves on each cylinder. In at least one cylinder, the rocker arms are inclined in opposite directions relative to an axis perpendicular to the camshaft. This arrangement counteracts thrust loads on the camshaft, helping reduce those loads and prevent axial movement.
Career Highlights
Ueda’s listed invention addresses a mechanical challenge in engine design: managing the forces that act on a camshaft as rocker arms operate the valves. The patent identifies Honda Motor Co., Ltd. as his company affiliation.
Collaborations
Masaru Kawano and Koji Katsumata are listed as Ueda’s coworkers. The available information does not specify their roles in developing or patenting the valve operating system.
Conclusion
Kei Ueda’s patent describes a rocker-arm arrangement intended to reduce camshaft thrust and limit axial movement in multicylinder engines.
