Abstract: A scroll compressor is provided that may include a first scroll, a second scroll that defines a plurality of compression chambers together with the first scroll, the second scroll having a discharge hole that communicates with a compression chamber among the plurality of compression chambers, a back pressure plate that defines a back pressure chamber to accommodate a refrigerant discharged from the discharge hole, a floating plate to define the back pressure chamber, and a sealing member to prevent the refrigerant from flowing between a first surface, which may be a sliding surface of the floating plate, and a second surface, which may face the first surface, of the back pressure plate. The sealing member may include a seal cover that contacts the other one of the first and second surfaces, and a seal, a portion of which may be accommodated in the seal cover. The seal cover may have a friction coefficient less than a friction coefficient of the seal.

Abstract: A scroll compressor having a scroll supporter and/or movement limiter is provided. The scroll compressor may include a casing, a main frame fixedly installed within the casing, a first scroll rotatably supported by the main frame, a second scroll supported by the main frame, such that the second scroll is movable in a vertical direction with respect to the first scroll, a guide that guides movement of the second scroll in the vertical direction, while preventing the second scroll from being rotated in an axial direction; and a movement limiter disposed on an inner wall of the casing and separated from the second scroll, the movement limiter being configured to limit a movement distance of the second scroll in an upward direction.
