Latest Patents

One of Kimura's latest patents focuses on the shape of suction and discharge holes in refrigerant compressors. This invention discloses holes designed to suppress turbulence in refrigerant gas flow. The tapered surface wall of the discharge hole increases in circumference from the piston cylinder surface to the discharge chamber surface. Similarly, the suction hole features a tapered design that enhances the flow path of the refrigerant gas, allowing it to flow tangentially to the valve reed. This innovation reduces flow resistance, improving the volume efficiency of the compressor while also suppressing noise.

Another notable patent involves a scroll member for scroll-type fluid machinery. This invention aims to enhance productivity in spiral machining and provides a cost-effective solution for scroll members. The design includes a spiral element formed around an axis and a base plate integrated into the end face of the spiral element. This configuration allows for efficient fluid compression by creating a fluid pocket between the spiral elements, which perform swing motion without relative rotation to a counterpart scroll member.
