Introduction

Jun Nakatsuji is a notable inventor based in Settsu, Japan. He has made significant contributions to the field of hydraulic systems, holding a total of 2 patents. His work focuses on enhancing the efficiency and functionality of hydraulic units.

Latest Patents

One of Nakatsuji's latest patents is a "Pump unit with multiple operation modes." This invention features a first pump of small capacity and a second pump of large capacity that are directly connected and driven by a variable-speed motor. The motor's rotational speed is controlled by a control device. In the first mode, the discharge lines of both pumps are disconnected, allowing the first pump to operate unloaded, which enables a constant-horsepower operation. In the second mode, the discharge lines are connected via a switching valve, allowing for a high flow rate of discharge fluid at a relatively low rotational speed.

Another significant patent is the "Load dependent variable speed hydraulic unit." This invention provides an autonomous inverter-driven hydraulic unit that can control pressure and flow rate without external input. The controller's target horsepower calculation unit assesses the current operating state and adjusts the motor's rotational speed to ensure that the present horsepower aligns with the target horsepower.
