Abstract
A scroll compressor includes a compression mechanism having fixed and movable scrolls forming a compression chamber, a motor to drive the movable scroll, a casing accommodating the compression mechanism and the motor, a housing accommodated inside the casing, a floating member supported by the housing, a first seal member, and first and second flow passages. An inside of the casing is partitioned into first and second spaces. The floater member can be pushed toward the movable scroll by pressure in a back-pressure space formed between the floating member and the housing. The first seal partitions the back-pressure space into first and second chambers. The first flow passage guides the refrigerant in the middle of compression in the compression mechanism to the first chamber. The second guides the refrigerant discharged from the compression mechanism to the second chamber.
