Title: Tomoaki Araki: Innovator in Rotary Valve Technology
Introduction
Tomoaki Araki is a notable inventor based in Gunma, Japan. He has made significant contributions to the field of valve technology, holding three patents that showcase his innovative spirit and technical expertise. His work primarily focuses on enhancing the functionality and efficiency of rotary valve systems.
Latest Patents
One of Araki's latest patents is the "Rotary Valve Actuator Arrangement." This invention includes a rotary valve and an electromagnetic actuator that actuates the rotary valve. The rotary valve features a valve shaft that is rotatable about an axis, with a valve body that rotates in unison with the shaft. The electromagnetic actuator consists of two stator cores, two coils wound on these cores, and a rotor that rotates around the axis, featuring two projecting portions that oppose the stator cores. The design allows for a continuously variable area that forms a magnetic path when the coil is energized.
Another significant patent is the "Throttle Valve Device," designed for internal combustion engines in automotive vehicles. This device comprises a throttle body that forms part of the intake air passageway. A throttle valve is mounted on a valve shaft and is rotatably positioned within the throttle body. The device includes a driving mechanism that connects to the throttle valve through a reduction gear mechanism, allowing for a speed reduction in the rotational movement. The design ensures that the throttle valve can transition smoothly between fully closed and fully opened positions, with a unique cam surface that allows for a partly opened position as well.
