  • Scroll compressor
    Patent number: 11221008
    Abstract: A scroll compressor is provided. An orbiting angle of the orbiting scroll when the compression chamber is formed and compression of fluid is initiated is referred to as an orbiting initiation angle. An orbiting angle of the orbiting scroll when the compression of the fluid is completed is referred to as an orbiting termination angle. An orbiting angle of the orbiting scroll when an end of the orbiting spiral wall initiates contact with the arcuate portion of the fixed spiral wall before compression is completed is referred to as a distal end contact initiation angle. The formation point distance reaches a minimum value at least at one of a first orbiting angle or a second orbiting angle.
    Type: Grant
    Filed: March 25, 2020
    Date of Patent: January 11, 2022
    Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKI

  • Scroll compressor
    Patent number: 11078909
    Abstract: A scroll compressor includes a fixed scroll and an orbiting scroll. An orbiting angle of the orbiting scroll when a compression chamber is formed and compression of fluid is initiated is referred to as an orbiting initiation angle. An orbiting angle of the orbiting scroll when the compression of the fluid is terminated is referred to as an orbiting termination angle. An orbiting angle of the orbiting scroll when an end of the orbiting spiral wall initiates contact with an arcuate portion of the fixed spiral wall is referred to as a distal end contact initiation angle. The formation point distance is a peak in at least one of orbiting angles obtained by subtracting integer multiples of 360° from an orbiting angle in a range from the distal end contact initiation angle to the orbiting termination angle.
