Title: Saburo Yoshio: Innovator in Hydraulic Control Systems
Introduction
Saburo Yoshio is a notable inventor based in Ibaraki, Japan. He has made significant contributions to the field of hydraulic control systems, particularly in the context of work vehicles. His innovative approach has led to advancements that enhance the efficiency and performance of hydraulic machinery.
Latest Patents
Yoshio holds a patent for a control device designed for hydraulically propelled work vehicles. This invention focuses on discriminating between the vehicle propulsion condition and the performing work condition. When the vehicle is in propulsion mode, the maximum engine revolution speed is limited to a first revolution speed, and the maximum displacement is restricted to a first displacement value. Conversely, during work performance, the maximum engine revolution speed is adjusted to a second, lower revolution speed, while the maximum displacement is increased to a second displacement value. This innovative design ensures that the pump output flow during vehicle propulsion is lower than during work performance, thereby reducing pressure loss and increasing output torque.
Career Highlights
Yoshio's career is marked by his role at Hitachi Construction Machinery Co., Ltd., where he has been instrumental in developing advanced hydraulic systems. His work has not only improved the functionality of construction machinery but has also contributed to the overall efficiency of hydraulic circuits.
