Title: Eiji Ejiri: Innovator in Torque Converter Technology
Introduction
Eiji Ejiri is a notable inventor based in Kanagawa Prefecture, Japan. He has made significant contributions to the field of automotive engineering, particularly in the development of torque converter technology. With a total of 3 patents to his name, Ejiri continues to push the boundaries of innovation in the automotive industry.
Latest Patents
Ejiri's latest patents include advancements in coreless torque converters. The first patent describes a coreless torque converter that features a pump impeller with coreless blades, each having a first leading edge directed forward. Additionally, the turbine runner is equipped with coreless blades that have a second leading edge directed rearward. The stator also includes coreless blades with front and rear edges facing the respective leading edges. Each leading edge extends generally straight, connecting the radially outward and inward terminal ends.
The second patent focuses on a torque converter of a coreless type that allows and utilizes fluid flow in a central core region. In this design, the impeller blade exit angle is smaller in the central core region compared to the outer region. This configuration increases the velocity and amount of fluid flow circulating in the outer region, which participates in torque multiplication, while decreasing the flow in the core region, similar to fluid flow in a fluid coupling.
