Title: Innovations of Yoshio Itakura

Introduction

Yoshio Itakura is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of compressor technology, holding two patents that showcase his innovative approach to engineering.

Latest Patents

One of his latest patents is a swash plate type compressor featuring a center cavity in the surface of the piston. This design includes shoes with center holes on the slidable surfaces, where the center hole acts as a reservoir for lubricating oil. This oil is supplied to the slidable surface of the shoe, which slides against the swash plate. The design also incorporates a second ring groove concentric to the center hole, or annexed grooves that stretch outward radially. Additionally, the center hole prevents the center part from protruding outward due to thermal expansion caused by friction. The slidable surface of the shoe is preferably coated with a layer containing solid lubricant to enhance the smoothness of the sliding motions.

Another significant patent by Itakura is a swash-plate-type compressor that includes suction and discharge damping chambers. This multi-cylinder compressor features a combined cylinder block that is closed on both axial ends by front and rear housings. It is equipped with a reciprocative piston mechanism for sucking, compressing, and discharging fluids, such as refrigerant gas. The design includes a mounting bracket on the outer circumference and suction and discharge ports positioned adjacent to the bracket. The damping chambers are strategically arranged to suppress pulsation in the suction and discharge pressures during operation, ensuring a more efficient performance.
