Title: Innovations of Kasumi Mishima

Introduction

Kasumi Mishima is a notable inventor based in Toyoake, Japan. She has made significant contributions to the field of engineering, particularly in the development of innovative valve systems. With a total of five patents to her name, her work has garnered attention for its practical applications in various industries.

Latest Patents

Mishima's latest patents include an eccentric valve and a fuel cell system. The eccentric valve features a drive mechanism, a drive force receiving part, a bearing for supporting a rotary shaft, and a return spring for generating a return spring force. During non-operation of the drive mechanism, this valve generates a separating-direction urging force that causes the rotary shaft to incline about the bearing, urging the valve element away from the valve seat. This design includes a sealing member to ensure a tight seal between the valve element and the valve seat during non-operation.

The fuel cell system utilizes an eccentric valve as an inlet sealing valve, which is equipped with a rubber seat designed to increase the surface pressure when the pressure in the air supply passage rises. This system also includes an outlet integration valve and a bypass valve, both of which are structurally similar to the inlet sealing valve. The controller manages the air supply to the fuel cell stack, ensuring efficient operation during vehicle deceleration.
