Abstract: A scroll compressor is disclosed. The scroll compressor may include an anti-rotation mechanism provided with an anti-rotation pin and an anti-rotation ring between an orbiting scroll and a scroll support member facing the orbiting scroll, and an axial thickness of the ring body portion constituting the anti-rotation ring may be larger than an axial depth of a ring insertion groove in which the anti-rotation ring is inserted. This can allow the orbiting scroll and a member facing the same to be spaced physically apart without a separate member, to secure a gap for oil to flow, such that the oil can be smoothly supplied between the orbiting scroll and the member, thereby suppressing seizure or/and friction loss between the orbiting scroll and the member.

Abstract: A motor operated compressor includes a drive motor and a rotary shaft coupled to the rotor. A first scroll disposed on one side of the drive motor is eccentrically coupled to and orbitally moved by the rotary shaft. A second scroll faces the first scroll and is coupled to the first scroll to form a compression chamber. A hollow portion is formed inside the rotary shaft along an axial direction, and an eccentric portion having a rotary shaft side discharge hole extends from the rotary shaft center to a rotary shaft outer circumferential surface. The first scroll includes a rotary shaft coupling portion surrounding an outer circumferential surface of the eccentric portion. The rotary shaft coupling portion is provided with a first scroll side discharge hole formed at a position periodically facing the rotary shaft side discharge hole to discharge compressed fluid to the rotary shaft side discharge hole.

Abstract: An electric compressor is disclosed. An electric compressor includes an oil separating member to effectively separate oil mixed in a compressed refrigerant. The oil separating member includes a compression guide part and an exhaust guide part. The oil mixed in the compressed refrigerant is separated by colliding with the compression guide part and the exhaust guide part. The compression guide part and the exhaust guide part form a refrigerant exhaust passage. The exhaust passage may have a diversified shape, such as a zigzag shape or a maze shape. The oil mixed in the compressed refrigerant is separated by its own weight while flowing through the exhaust passage. Accordingly, oil separation efficiency of the electric compressor can be improved.
