Abstract: A compressor according to the present invention comprises a hinge recess formed at a rolling piston and a hinge protrusion formed at a vane to be inserted into the hinge recess. A diameter of the hinge protrusion is greater than an interval between both ends of an opening of the hinge recess. A bearing surface, which comes in contact with an inner circumferential surface of the hinge recess, of an outer circumferential surface of the hinge protrusion, has a circumferential surface below 90° at both sides, respectively, based on a central line in a lengthwise direction of the vane. This structure may facilitate for cutting and grinding the bearing surface so as to reduce a machining cost, and also improve a machining degree and thus stabilize behaviors of the rolling piston and the vane so as to enhance compression efficiency.

Abstract: Disclosed is a compressor. A lubrication surface, which has the same curvature as an inner circumferential surface curvature of a cylinder and which has a predetermined circumference length, is formed on an outer circumferential surface of a roller contacting an inner circumferential surface of the cylinder. With such a configuration, since the outer circumferential surface of the roller contacting the inner circumferential surface of the cylinder come in surface-contact with each other, an oil film is formed between the roller and the cylinder with a wide area. This can reduce a frictional loss.

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.
