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.
Career Highlights
Throughout his career, Hideo Konishi has worked with prominent companies such as Jidosha Kiki Co., Ltd. and Bosch Braking Systems Co., Ltd. His experience in these organizations has allowed him to refine his skills and contribute to advancements in pump technology.
