Abstract

A scroll compressor is provided that may include a casing; an electric motor drive having a stator fixed within the casing, and a rotor rotatably provided within the stator; a rotational shall coupled to the rotor to rotate along with the rotor; a compression device disposed at a lower portion of the electric motor drive to receive a rotational force from the rotational shaft and compress a refrigerant; and an oil storage space located within the casing. A plurality of oil discharge paths to allow oil accumulated at an upper portion thereof to be discharged to the oil storage space may be formed on an outer circumferential surface of the compression device to be separated from each other, and an overall cross-sectional area of the plurality of oil discharge paths may be about 2 to about 12% of an inner diameter cross-sectional area of the casing brought into contact with or separated from an outer circumferential surface of the compression device in the compression device.
