Abstract: A scroll compressor may include a casing (110) having a sealed inner space; a drive motor (120) provided in the inner space of the casing to generate a rotational force; a rotating shaft (160) coupled to a rotor of drive motor to rotate; an orbiting scroll (150) formed of an aluminum material, and coupled to the rotating shaft to perform an orbiting movement; a fixed scroll (140) coupled to the orbiting scroll to form a compression space consisting of a suction chamber, an intermediate pressure chamber and a discharge chamber; and a rotation prevention member (170) coupled to the orbiting scroll, and formed of a sintered metal. As a result, it may be possible to prevent an Oldham ring from being worn out due to contact with the orbiting scroll. Furthermore, a weight loss portion or wear-resistant coating layer may be formed on a part of the Oldham ring, thereby suppressing a vibration noise of the compressor from being increased due to a weight increase of the Oldham ring.

Abstract: A scroll compressor includes: a casing (110); a driving motor (120); a fixed scroll (140) which forms a compression space having a suction chamber, an intermediate pressure chamber and a discharge chamber, by being coupled to the orbiting scroll (150); and a discharge cover (190) installed at an inner space of the casing, having a space portion (191) communicated with a discharge chamber by being separated from the inner space of the casing, and having one or more discharge holes (195) on a side surface of the space portion corresponding to an inner wall surface of the casing, among surfaces of the space portion, the discharge hole for communicating inside and outside of the space portion with each other. With such a configuration, vibration noise of the compressor may be more reduced than in a case where an oil separator is installed outside the casing. Further, as an area of the discharge hole and a volume of the space portion are optimized, efficiency of the compressor may be enhanced.
