Title: Hiromichi Tsugami: Innovator in Throttle Body Technology

Introduction

Hiromichi Tsugami is a notable inventor based in Chiyoda-ku, Japan. He has made significant contributions to the field of throttle body technology, holding a total of 6 patents. His work focuses on enhancing the performance and efficiency of internal combustion engines.

Latest Patents

One of Tsugami's latest patents is the "Throttle body for internal combustion engine." This invention features a throttle body that rotates a valve shaft of an air-intake throttle valve through a decelerating mechanism powered by a motor. It allows for the adjustment of the opening area of the air-intake passage by rotating the valve shaft. The design includes a lever portion that interlocks with the decelerating mechanism, regulating the opening degree of the throttle valve in its full-open state. Additionally, an adjusting screw is threadably inserted from the outside of the body to change the opening degree of the throttle valve.

Another significant patent is the "Electronically-controlled throttle body." This invention comprises a throttle valve with a valve disc fixed on a rotatable valve shaft within a body that forms an air-intake passage. The throttle body includes a reduction gear mechanism connected to the valve shaft and a motor that drives the mechanism. The rotational power from the motor is transmitted to the valve shaft via the reduction gear mechanism, allowing for the variation of the opening area of the air-intake passage by moving the valve disc. The reduction gear mechanism employs both a planetary gear mechanism and a spur gear reduction gear mechanism to decelerate the motor's rotational drive power before it reaches the valve shaft.
