Abstract: A horizontal type rotary compressor includes a case including an inlet and an outlet and configured to store oil, a compressor having a compression space in which refrigerant is accommodated, a driver to drive the compressor, a rotating shaft to connect the driver and the compressor, an oil feed pipe disposed at a side of the compressor, a first plate configured to divide the case into a first area for the driver and a second area for the compressor. The first plate including a discharge hole through which compressed refrigerant is discharged from the compressor to the first area. A second plate dividing the case into the second area and a third area in which the oil feed pipe communicates with the outlet, and includes a second hole formed at the upper side to communicate the second and third areas. The first and second plates forming an oil flow path.

Abstract: A rotary compressor includes a rotary shaft rotating in a first direction and defining each of an oil channel along which oil moves, an oil hole corresponding to a cylinder and a gas hole above the cylinder, and an oil paddle rotating in the first rotation direction together with the rotary shaft, the oil paddle including a first length region twisted in a second rotation direction opposite to the first rotation direction, and a second length region twisted in the first rotation direction, where rotation of the rotary shaft in the first rotation direction includes the first length region of the oil paddle transferring the oil along the oil channel and toward the gas hole, together with the second length region of the rotary shaft transferring the oil along the oil channel and away from the gas discharge hole.

Abstract: This rotary compressor comprises: a casing forming the outer shape; a rolling piston configured to rotate eccentrically in an internal space; a vane configured to contact the rolling piston and divide the internal space into a suction chamber and a compression chamber; and a main suction port connecting the suction chamber to an outside of the cylinder. The rotary compressor also comprises: a cylinder disposed inside the casing; a first flange disposed above the cylinder; and a second flange disposed below the cylinder. The main suction port comprises a sub suction port extending in a direction in which at least one among the first flange and the second flange is disposed, and at least one among the first flange and the second flange has a flow path groove connecting the sub suction port and the suction chamber.
