Introduction

Shinichi Hirai is a notable inventor based in Wako, Japan. He has made significant contributions to the field of hydraulic devices, holding a total of 2 patents. His work reflects a deep understanding of hydraulic control systems and their applications in various industries.

Latest Patents

One of Hirai's latest patents is a hydraulic device that controls pulsation in the first oil by increasing the rotation number of a second pump. In this hydraulic control device, when the output pressure detected by an output pressure sensor pulsates, a transmission control unit (TCU) either stops the driving of the second pump or decreases its rotation number as a first operation. Alternatively, if the output pressure pulsates, the TCU increases the rotation number of the second pump to a level higher than the target rotation number as a second operation. Another significant patent is for a gear pump, where a driving rotor meshes with a driven rotor to pump hydraulic oil. In this design, only one of the rotors is subjected to steam treatment while the other remains untreated, enhancing the efficiency of the pump.
