Abstract: A scroll compressor is provided that may have a first sealing portion defined between an inner surface of an orbiting wrap and an outer surface of a non-orbiting wrap facing the inner surface of the orbiting wrap in a radial direction, and a second sealing portion defined between an inner surface of the non-orbiting wrap and an outer surface of the orbiting wrap facing the inner surface of the non-orbiting wrap in the radial direction. Further, sealing surfaces where the wraps facing each other are in surface-contact with each other may be formed on at least one of the first sealing portion or the second sealing portion. This may enlarge a sealing area between side surfaces of the wraps facing each other to suppress or prevent leakage of refrigerant suctioned in a compression chamber, thereby improving indicated efficiency and volumetric efficiency.

Abstract: A scroll compressor is provided that may include a first back pressure unit that allows a refrigerant to flow from a first compression chamber to a back pressure chamber while blocking a reverse flow of the refrigerant, and a second back pressure unit that allows the refrigerant to flow from the back pressure chamber to a second compression chamber while blocking a reverse flow of the refrigerant. The first back pressure unit and the second back pressure unit may be spaced apart from each other in a direction that the compression chambers are formed. This may reduce pressure pulsation in the back pressure chamber. Also, leakage between compression chambers may be suppressed and simultaneously friction loss may be reduced by appropriately adjusting the pressure in the back pressure chamber. This is especially advantageous for enhancing compression efficiency under low load operating conditions (or in a low pressure ratio operation).

Abstract: A scroll compressor is disclosed. The scroll compressor may include a suction guide between a refrigerant suction pipe and a high/low pressure separation plate, and the suction guide may be fastened to a non-orbiting scroll or inserted into a suction guide protrusion that extends from the non-orbiting scroll. Accordingly, suction refrigerant may be partially suctioned into a compression chamber by the suction guide in advance before moving to the high/low pressure separation plate, so as to be prevented from coming into contact with the high/low pressure separation plate, while the suction refrigerant may also partially flow toward a drive motor without being suctioned directly into the compression chamber, so as to cool the drive motor, whereby efficiency of the compressor may be improved and an operation range of the compressor may be expanded.

Abstract: A scroll compressor is provided that may include first and second variable-capacity units that provide communication between a first intermediate pressure chamber and a low-pressure portion and between a second intermediate pressure chamber and the low-pressure portion. The first variable-capacity unit may include a first variable-capacity passage that communicates with the intermediate pressure chamber, at least one first variable-capacity valve that opens/closes the first variable-capacity passage, and a first variable-capacity opening and closing valve that controls opening/closing of the at least one first variable-capacity valve, and the second variable-capacity unit may include a second variable-capacity passage that communicates with a second intermediate pressure chamber, at least one second variable-capacity valve that opens/closes the second variable-capacity passage, and a second variable-capacity opening and closing valve that controls opening/closing of the at least one second variable-capacity valve.

Abstract: A scroll compressor includes a discharge guide disposed in a high-pressure part to guide refrigerant discharged from a compression part to a refrigerant discharge pipe, and the discharge guide may extend by a preset height from an inner circumferential surface of a casing constituting the high-pressure part toward one side surface of a high and low pressure separation plate. This can guide discharge refrigerant discharged to the high-pressure part to quickly flow to the refrigerant discharge pipe before being spread in an entire space of the high-pressure part, thereby preventing the high and low pressure separation plate from being overheated by discharge refrigerant of high temperature. This can result in preventing suction refrigerant of a low-pressure part from being heated by heat of discharge refrigerant transferred through the high and low pressure separation plate, thereby reducing a specific volume of the suction refrigerant and improving compressor efficiency.
