Abstract:
A hermetic scroll compressor has a symmetric wrap structure. The scroll compressor includes fixed and movable scrolls, a crank shaft, a motor, and a casing. The casing includes an oil reservoir, and a motor space serving as a low-pressure space. The fixed and movable scrolls define first and second compression chambers. The fixed scroll has a first passage to guide gas refrigerant in the low-pressure space to the first and second compression chambers. The movable scroll has a second passage to guide gas refrigerant in the low-pressure space to the first compression chamber. The gas refrigerant that has passed through the first and second passages flows into the first compression chamber. The gas refrigerant that has passed through the first passage also flows into the second compression chamber.
