Title: The Innovative Contributions of Shinichi Hagidaira

Introduction

Shinichi Hagidaira is a notable inventor based in Gifu, Japan. He has made significant contributions to the field of engineering, particularly in the development of solenoid valves. With a total of nine patents to his name, Hagidaira's work showcases his expertise and innovative spirit.

Latest Patents

One of his latest patents involves a solenoid valve that features a main valve with a valve seat and a main valve body designed to open or close a main flow passage. This invention includes a pilot passage branching from the main flow passage, an orifice in the pilot passage, and a back-pressure chamber that biases the main valve body towards a closing direction due to internal pressure. The pilot valve controls the internal pressure of the back-pressure chamber, while a solenoid regulates the valve opening pressure of the pilot valve. Notably, there is a time difference between the valve opening timing of the main valve and that of the pilot valve, ensuring that the main valve opens later than the pilot valve.

Another patent by Hagidaira also focuses on a solenoid valve, which includes a valve seat in the main flow passage and a main valve body that can open or close this passage. Similar to his previous invention, this design features a pilot passage, an orifice, and a back-pressure chamber that influences the main valve body. The pilot valve, located downstream from the back-pressure chamber, manages the internal pressure, while a solenoid controls the valve opening pressure of the pilot valve. Additionally, a second orifice is included between the back-pressure chamber and the pilot valve.
