Title: **The Innovations of Toshihiro Tsutsui: A Visionary Inventor from Wako, Japan**

Introduction

Toshihiro Tsutsui is a prominent inventor based in Wako, Japan, known for his significant contributions to the field of engineering. With a total of seven patents to his name, Tsutsui has focused on advancements in fuel supply systems and Rankine cycle apparatuses, demonstrating a commitment to innovation that enhances the efficiency of internal combustion engines and thermal energy systems.

Latest Patents

Tsutsui's latest inventions include a **Fuel Supply Device for Internal Combustion Engine** and a **Rankine Cycle Apparatus**. The fuel supply device is designed to transport fuel from the tank to the injector by employing a diaphragm pump that utilizes pressure variation within the crankcase. This innovative diaphragm pump consists of a pump casing, a diaphragm that separates the pump’s interior into a negative pressure chamber and a pump chamber, and a plunger that moves reciprocally to facilitate fuel transfer. A critical aspect of this invention is that the pressure receiving area from which the plunger operates is smaller than the area affecting the diaphragm, ensuring optimal performance and functionality.

The Rankine cycle apparatus addresses a common issue in closed working medium circulation circuits. It handles excessive pressure that may arise in either an expander or evaporator by discharging the water-phase working medium through relief valves, thereby maintaining safe operational levels. This meticulous approach not only prevents equipment failure but also promotes the reliability of thermal energy systems.
