Abstract: A scroll compressor is provided. The scroll compressor includes a fixed scroll having an outlet and multiple release holes, a release valve ring installed on the top surface of the fixed scroll and formed to open and close the multiple release holes, and a retainer ring installed on the release valve ring and formed to restrict the movement of the release valve ring. The release valve ring has a ring shape, and comprises a fixing part, multiple release valves, and at least one connection part. The retainer ring comprises a retainer fixing part, multiple retainers, and at least one retainer connection part connecting at least one of the multiple retainers to the retainer fixing part.

Abstract: Provided is a scroll compressor with enhanced sealing structure of a back pressure chamber. The scroll compressor includes a housing, a fixed scroll fixed to inside of the housing and including a fixed wrap, an orbit scroll including an orbit wrap which forms a compression chamber together with the fixed wrap, a back pressure chamber formed at a frame supporting the orbit scroll, and accommodating refrigerant for pressurizing the orbit scroll to a direction of the fixed scroll, and a sealing ring arranged between the fixed scroll and the orbit scroll to prevent the refrigerant in the back pressure chamber from flowing in or out through a gap between the fixed scroll and the orbit scroll, wherein the sealing ring includes a cut portion cut for the sealing ring to be deformable in a circumferential direction.

Abstract: A scroll compressor includes a main body, a cover to divide the main body into a low pressure section and a high pressure section, a fixed scroll including a first discharge port, an orbiting scroll to rotate with respect to the fixed scroll and to form a compression chamber together with the fixed scroll, a discharge guide disposed between the fixed scroll and the cover and including a second discharge port connected to the first discharge port, and a back pressure actuator configured to form a back pressure chamber together with the discharge guide and to move in a direction toward the cover with respect to the discharge guide to selectively connect the second discharge port with the high pressure section. The fixed scroll includes a bypass flow path connecting the compression chamber and the second discharge port and a bypass valve to open or close the bypass flow path.
