Title: Norihisa Katafuchi: Innovator in Pump Technology

Introduction

Norihisa Katafuchi is a notable inventor based in Okazaki, Japan. He has made significant contributions to the field of pump technology, particularly with his innovative designs that enhance efficiency and reduce fluid leaks.

Latest Patents

Katafuchi holds a patent for a tandem rotary pump with a pressure chamber between two intermediate sides. This invention features a pump housing that contains a pair of pump rotors rotating as a single unit with a rotating shaft. A series of vanes are mounted on these rotors, dividing the internal space of each cam ring into multiple pump chambers. An intermediate side plate is strategically positioned between the cam rings, which are secured between one wall of the pump housing and a rear side plate. The intermediate side plate consists of two side plates that are in contact with each other, with a recess formed in the inner peripheral part of one side, creating a pressure chamber. The pressure fluid discharged from the pump chamber is directed into this pressure chamber, allowing the inner peripheral part of each side plate to elastically deflect under fluid pressure, thereby minimizing gaps and preventing fluid leaks.
