Abstract: A scroll compressor can include a frame including a shaft hole, a fixed scroll on an upper side of the frame, an orbiting scroll between the fixed scroll and the frame, a lower surface of the orbiting scroll including a boss inserted into the shaft hole, a rotatable shaft including an eccentric portion inserted into the boss and inserted into the shaft hole, a first bearing in the shaft hole between the shaft hole and a bearing support coupled to an outer circumferential surface of the rotating shaft, an inner circumferential surface of the first bearing being supported by an outer circumferential surface of the bearing support, the bearing support being separatable from, and couplable to, the rotating shaft, and a second bearing between the boss and the eccentric portion so that a location of the second bearing overlaps the first bearing in an axial direction of the rotatable shaft.

Abstract: A scroll compressor is provided. The scroll compressor includes a fixed scroll, an orbiting scroll configured to orbit with respect to the fixed scroll and including an orbiting end plate, and a main frame to which the orbiting scroll is coupled to orbit. The scroll compressor includes a compression chamber in which a refrigerant is compressed by the fixed scroll and the orbiting scroll, and a first back pressure chamber and a second back pressure chamber provided to communicate with the compression chamber. The first back pressure chamber and the compression chamber communicate with each other through a first flow path. The second back pressure chamber and the compression chamber communicate with each other through a second flow path. A different intermediate back pressure is formed in the first back pressure chamber and the second back pressure chamber.
