Title: Hideo Konishi: Innovator in Variable Displacement Pump Technology

Introduction

Hideo Konishi is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of pump technology, particularly with his innovative designs for variable displacement pumps. With a total of 8 patents to his name, Konishi has established himself as a key figure in engineering and invention.

Latest Patents

One of Konishi's latest patents involves a variable displacement pump that features a cam ring slidably supported within a pump body. A rotor is rotatably disposed inside the cam ring, which is eccentric to the rotation shaft of the rotor. The rotor carries multiple vanes that can be advanced or retreated, forming a pump chamber in the space between the cam ring and the rotor. The cam ring is designed with first and second fluid pressure chambers on both sides, biased by a spring to maximize the pump chamber's displacement. A control valve is integrated, applying differential pressure across a metering orifice on both ends of a spool, with a spring positioned on the side where downstream fluid pressure is applied. The fluid pressures in the chambers are controlled by the valve, allowing the cam ring to swing. Additionally, a piston responds to increases in working pressure from a power steering apparatus, exerting axial thrust on the spool's end face.
