With a total of two patents to his name, Inaba's inventions focus on improving the efficiency and functionality of scroll compressors, which are widely used in various cooling and refrigeration applications.

Latest Patents

Inaba's innovation in scroll compressors addresses critical problems in their operation. His first patent presents a scroll compressor designed to enhance workability by effectively communicating between the back pressure chamber and the compression chamber. This invention includes a back pressure chamber formed on the back surface of a movable scroll’s mirror plate, featuring a communication hole that connects both chambers. This ingenious design incorporates a large-diameter hole section situated on the back pressure chamber side and a smaller section that extends to the compression chamber, ensuring optimal performance.

In his second patent, Inaba tackles the issue of localized contact caused by the deformation of the fixed and movable scrolls under compressive reaction forces or thermal expansion. His solution involves a design where the laps and of both scrolls feature multiple step portions between their winding end and start. These step portions decrease in height towards the winding start, strategically placed to maintain a predetermined arc when expanded on a specific plane. This innovation not only prevents localized contact but also shortens the break-in time of the compressor, further enhancing its efficiency.
