Title: Yutaka Takeuchi: Innovator in Throttle Valve Technology

Introduction

Yutaka Takeuchi is a notable inventor based in Hitachinaka, Japan, who has made significant contributions to the field of automotive engineering. With a total of six patents to his name, Takeuchi's innovations focus primarily on enhancing the functionality and efficiency of throttle systems in vehicles.

Latest Patents

Among his latest patents, one stands out for its inventive approach to throttle body design. The lightweight, low-cost throttle body incorporates a throttle valve made from resins that effectively address the issue of excessively large gap formation. The design employs circumferentially oriented fillers within the resin, aligning the radial linear expansion coefficient of the throttle valve with that of the bore. Additionally, grooves on concentric circles in the throttle valve facilitate this orientation, enhancing operational reliability.

Another prominent patent relates to a throttle valve opening and closing device. This invention aims to simplify the default mechanism of the throttle valve for improved mountability. In scenarios where a motor generates no driving force, the throttle valve is held in position by a return spring. This innovative design minimizes gaps between the throttle valve and the wall surface of the intake passage by incorporating spherical recesses that align with the throttle valve when in operation, optimizing performance across a range of conditions.
