  • Publication number: 20240191712
    Abstract: A scroll compressor includes a fixed scroll and a movable scroll. A facing surface of the fixed scroll that faces the movable scroll has a fixed oil groove. The fixed oil groove has a fixed circumferential groove portion. The fixed circumferential groove portion has a circular-arc portion that extends in the circumferential direction, and a wide portion wider in a radial direction than a groove width of the circular-arc portion. A facing surface of the movable scroll that faces the fixed scroll has a movable oil groove. The movable oil groove has a movable circumferential groove portion, and a radial groove portion that communicates with the movable circumferential groove portion. In a predetermined region of an angle range where the movable scroll makes an orbiting motion, a portion of the radial groove portion overlaps the wide portion as viewed from an axial direction.

  • Patent number: 11125230
    Abstract: A scroll compressor includes fixed and movable scrolls defining a compression chamber, and a crankshaft. The movable scroll at least partially covers a discharge port formed in the fixed scroll to change a communication area that is a portion of a total area of the discharge port that contributes to communication with the compression chamber. First to third rotation angle positions become larger in order. As the crankshaft rotates from the first to second rotation angle position the communication area increases at a first rate. In the first rotation angle position the compression chamber and the discharge port start communicating with each other. The second rotation angle position is a preliminary discharge interval angle. As the crankshaft rotates from the second to third rotation angle position the communication area increases at a second rate. The second rate of increase is greater than the first rate of increase.

  • Patent number: 11047384
    Abstract: A scroll compressor includes fixed and orbiting scrolls, and satisfies at least one of a first condition and a second condition. In the first condition, a first gap between a distal end of the first wrap and the second base changes heading from an outer peripheral side of the first wrap to an inner peripheral side. In the second condition, a second gap between a distal end of the second wrap and the first base changes heading from an outer peripheral side of the second wrap to an inner peripheral side. A rate of change in the first gap in one area is greater than a rate of change in the first gap in another area. A rate of change in the second gap in one area is greater than a rate of change in the second gap in another area.
