Title: Yasunori Makino: Innovator in Variable Displacement Compressors

Introduction

Yasunori Makino is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of compressor technology, holding a total of four patents. His innovative designs focus on enhancing the efficiency and functionality of variable displacement compressors.

Latest Patents

One of Makino's latest patents is a variable displacement compressor that decreases displacement to reduce compression load without causing an imbalance in the rotation of the drive shaft when the rotating speed exceeds a predetermined limit. This compressor features a pressurizing passage that connects a crank chamber to a discharge chamber. A rotated guide, which rotates integrally with the drive shaft, plays a crucial role in the operation of the compressor. The pressurizing passage is controlled by a valve body, while orbiting balls, arranged around the drive shaft and the rotated guide, follow the rotation and vary their orbiting radius. A spring mechanism urges the balls to decrease their orbiting radius, but when the drive shaft's speed exceeds the limit, centrifugal force moves the balls outward, increasing the size of the pressurizing passage.

Another patent by Makino describes a variable type compressor that includes a housing with a crank chamber and a rotatably supported drive shaft. The housing contains a cylinder block with cylinder bores extending around the drive shaft. Each cylinder bore accommodates a piston that draws refrigerant gas from a suction chamber and discharges it into a discharge chamber. The displacement and discharge of the refrigerant gas are controlled by altering the inclination of an inclinable cam plate. Additionally, a collection compartment is provided to receive the discharged refrigerant gas, where oil is separated before being supplied back to the crank chamber.
