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 hermetic compressor including a casing; a motor inside the casing, and including a rotor and stator; a drive shaft that rotates with the rotor; a compression unit below the motor to compress refrigerant and discharge compressed refrigerant to an inside of the casing; and an oil blocking guide above the motor to rotate with the rotor. The oil blocking guide includes an oil blocking plate formed in a disk shape, an oil guide part extending outward and upward from an edge of the oil blocking plate, and a support part connecting the oil blocking plate to the drive shaft and space the oil blocking plate from the rotor. The oil blocking plate and the oil guide part block upward movement of oil passing through the motor, and guide the oil to an inner circumferential surface of the casing through centrifugal force while the oil blocking guide is rotating.
