Title: Satoshi Chikamatsu: Innovator in Solenoid Valve Technology

Introduction

Satoshi Chikamatsu is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of solenoid valve technology, holding a total of 5 patents. His innovative designs have advanced the functionality and efficiency of solenoid valves in various applications.

Latest Patents

Chikamatsu's latest patents include a sophisticated solenoid valve design. This solenoid valve features a main valve with a valve seat and a main valve body that can open or close a main flow passage. It incorporates 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. Additionally, it includes a pilot valve that controls the internal pressure of the back-pressure chamber and a solenoid that regulates the valve opening pressure of the pilot valve. Notably, there is a time difference between the valve opening timings of the main valve and the pilot valve, ensuring that the main valve opens later than the pilot valve.

Another patent by Chikamatsu describes a solenoid valve that includes a valve seat in the main flow passage and a main valve body for controlling the flow. This design also features a pilot passage, an orifice, and a back-pressure chamber that influences the main valve body. The pilot valve is strategically placed downstream to manage the internal pressure of the back-pressure chamber, while a solenoid controls the valve opening pressure of the pilot valve. A second orifice is also included between the back-pressure chamber and the pilot valve, enhancing the valve's operational efficiency.
