  • Rotary compressor having a combined vane-roller structure including a ferrosoferric oxide film on a surface of a coupling groove of the roller
    Patent number: 11555404
    Abstract: A rotary compressor has a combined vane-roller structure that may ensure improved productivity and reliability through control of mechanical properties. The rotary compressor includes a coupling groove which is disposed at one side of an outer circumferential surface of the roller, which has a circular arc shape from an outer diameter of the roller towards an inner diameter of the roller, and which is configured to couple a vane and the roller, and includes a ferrosoferric oxide (Fe3O4) film on a surface of the coupling groove. A manufacturing method of the rotary compressor is also described.
