Title: Shinichi Kagawa: Shock Absorber Inventor

Introduction

Shinichi Kagawa is an inventor based in Ayase, Japan. His work includes shock absorber technology, and he is associated with Hitachi Automotive Systems, Ltd. Kagawa is credited with 4 patents.

Latest Patents

Kagawa’s latest patent describes a shock absorber that uses a pilot-type main valve and a pressure-control pilot valve to regulate hydraulic oil flow and generate damping force. A solenoid adjusts the pilot valve’s opening pressure, which in turn controls pressure in a back-pressure chamber and the opening pressure of the main valve.

The design also includes a baffle plate in the reservoir. It separates the hydraulic-oil surface from the inlet through which oil returns from the damping-force mechanism, helping suppress aeration and cavitation. The plate is secured using a positioning opening and connecting port, while paired arm portions hold a separator tube.

Career Highlights

Kagawa’s patent work focuses on components and fluid-control mechanisms for vehicle suspension systems. His shock absorber invention combines adjustable valve control with a reservoir arrangement intended to improve hydraulic operation.
