Abstract
A scroll compressor includes a fixed scroll, an orbiting scroll, a crankshaft rotationally supported on a frame to drive the orbiting scroll, a seal member between an orbiting scroll back surface and the frame, a back pressure chamber of discharge pressure at an inner peripheral side of the seal member, another back pressure chamber of low pressure at an outer peripheral side so that the orbiting scroll is pressed against the fixed scroll with the pressures of these back pressure chambers, and a guide ring supporting an end surface of the seal member at a side opposite to the orbiting scroll and including a guide portion guiding an inner peripheral surface of the seal member so that the seal member is brought into close contact with the orbiting scroll back surface by a wave spring through the guide ring.
