Title: Innovations by Yoshihito Iwasaki

Introduction

Yoshihito Iwasaki is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of hydraulic systems, particularly in the design of concrete agitating drum driving devices. With a total of 3 patents to his name, Iwasaki continues to push the boundaries of innovation in his industry.

Latest Patents

Iwasaki's latest patents include a concrete agitating drum driving device that utilizes a hydraulic motor. This device features a connection switch-over valve that regulates the flow cross-sectional area of pressurized working oil supplied to the hydraulic motor from a variable capacity hydraulic pump. The pump is driven by a combustion engine along with a charge pump. When the discharge pressure of the charge pump is low, the connection switch-over valve maintains a small flow cross-sectional area, allowing the agitating drum to rotate at a low speed, thereby minimizing fuel consumption. Conversely, when the discharge pressure increases, the valve enlarges the flow area to achieve the rated rotation speed of the agitating drum.

Another patent describes a variable capacity hydraulic pump that drives a concrete agitating drum via a hydraulic motor. In this design, a hydraulic actuator regulates the discharge flow rate of the hydraulic pump based on the actuator driving pressure. A load sensing valve generates this pressure by reducing the discharge pressure of the hydraulic pump according to the differential pressure between the discharge pressure and the load pressure acting on the hydraulic motor. A shut-off valve is included to control the supply of pressurized oil to the hydraulic motor, preventing excessive noise from the hydraulic pump.
