Title: The Innovations of Shoichiro Sakurai

Introduction

Shoichiro Sakurai is a notable inventor based in Hitachi, Japan. He has made significant contributions to the field of carburetor technology, particularly with his innovative designs that enhance engine performance.

Latest Patents

Sakurai holds a patent for an altitude compensating device for carburetors. This device features an air metering valve that is in fluid communication with the fuel passage of the carburetor. It utilizes a pressure-sensitive bellows to control the air metering valve, allowing for an increased flow rate of compensating air as altitude rises. The design includes a closed control air chamber located upstream of the air metering valve. Venturi vacuum around the venturi portion of the intake passage introduces air into the control air chamber, reducing pressure below atmospheric levels as intake air flow increases. This mechanism effectively decreases compensating air to eliminate undesirable low concentration tendencies in the fuel mixture.
