  • Patent number: 12018686
    Abstract: A rotary compressor is provided that may include a cylinder having an inner peripheral surface; a roller; and a plurality of vanes slidably inserted into the plurality of vane slots to rotate together with the roller, front end surfaces of which come into contact with the inner peripheral surface of the cylinder due to the back pressure to partition the compression space into a plurality of compression chambers. The cylinder may further include a suction flow path for refrigerant that may include a suction port that communicates with the compression space to suction the refrigerant in a lateral direction, and a suction passage disposed in a direction that crosses the suction port to provide communication between the compression space and the suction port.

  • Publication number: 20240151231
    Abstract: A rotary compressor is provided that may include a casing having an oil storage space; a cylinder; a main bearing and a sub bearing; a rotary shaft; a roller having a vane slot and a back pressure chamber; and at least one vane. An oil supply hole that communicates the back pressure chamber with the oil storage space may pass through the main bearing or the sub bearing, or through the roller. Accordingly, as high-pressure oil is supplied directly to a rear end surface of the vane, it is possible to increase efficiency of the compressor by increasing a back pressure on the vane and suppressing a delay in starting the compressor, and it is also possible to reduce collision noise and wear in the vane and the cylinder by suppressing vibration of the vane.

  • Publication number: 20230349382
    Abstract: A rotary compressor is disclosed. A back pressure pocket among a plurality of back pressure pockets closest to a discharge port disposed in at least one of main bearing or sub bearing is radially spaced from an inner circumferential surface of a bearing hole, and communicates with an inner space of a casing through a back pressure passage formed through at least one of the main bearing or the sub bearing. Accordingly, the back pressure pocket closest to the discharge port may strongly support a vane passing near a reference point toward a cylinder while forming a discharge pressure, or a super discharge pressure higher than the discharge pressure. This may suppress or prevent chattering of the vane near the reference point to reduce vibration noise while suppressing or preventing wear between the vane and the cylinder to enhance compression efficiency. This may also suppress or prevent leakage between compression chambers, thereby preventing delay of initial startup of the compressor.
