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 co-rotating scroll compressor is provided in which pressure differences between inner and outer portions of a suction chamber are maintained, back pressures are applied to rear surfaces of end plates of a drive scroll and a driven scroll in directions in which the two scrolls are moved toward each other to prevent compression leakage of a fluid, and a lubricant oil is easily supplied to the two scrolls using the back pressures. The co-rotating scroll compressor may include pressure seals between the rear surfaces of the end plates of the drive scroll and the driven scroll and an inner wall of the suction chamber such that the two scrolls are pressed in directions to be moved toward each other by the back pressures, and the oil is supplied to rotary supports and close contact portions of the two scrolls using the back pressures.

Abstract: A scroll compressor is provided that may include a casing; a drive motor; a fixed scroll that forms a compression space by being coupled to the orbiting scroll; and a discharge cover provided at an inner space of the casing, the discharge cover having a space that communicates with the compression space and separated from the inner space of the casing, and having one or more discharge hole on a side surface thereof, the one or more discharge hole providing communication between an inside and an outside of the space. With such a configuration, vibration noise of the scroll compressor may be more reduced in comparison with a case in which an oil separator is provided outside of the casing. Further, as an area of the one or more discharge hole and a volume of the space are optimized, efficiency of the scroll compressor may be enhanced.

Abstract: A scroll compressor is provided that may include a casing, an orbiting scroll and a non-orbiting scroll that suctions in a refrigerant from a suction space of the casing, compress the sectioned refrigerant in a plurally of compression chambers, and discharge the compressed refrigerant into a discharge space of the casing, and a capacity varying device having a first valve and at least one second valve coupled with each other inside of the casing to selectively bypass a portion of the refrigerant in the plurality of compression chambers. With this structure, it is possible to prevent, in advance, refrigerant from being leaked outside of the scroll compressor, reduce pressure loss as a bypass flow path is shortened, reduce a size, weight, and manufacturing costs of the scroll compressor, and vary a capacity of the scroll compressor with a small operating force, and small power consumption.
