SCROLL COMPRESSOR

PROBLEM TO BE SOLVED: To secure a supply passage of a refrigerant into a compression space for preventing seizure of a fixed scroll and a rocking scroll in antiphase operation of a scroll compressor, and to early stop the antiphase operation of the scroll compressor for preventing abrasion of a sliding part of the scroll compressor.SOLUTION: This scroll compressor 100 includes a chamber room 31 communicating with a delivery port 1d, a delivery valve device 20 for opening-closing a second delivery port 21 communicating with the chamber room 31, a chamber room inside check valve device 34 for allowing a flow of the refrigerant to the chamber room 31 from a low pressure space of a compression mechanism part via a communicating hole 33 arranged in the fixed scroll 1 in the antiphase operation, a communicating passage 24 for allowing the flow of the refrigerant to the chamber room 31 from a sealed vessel inside space 10a, and a frame part check valve device 40 for allowing the flow of the refrigerant to the sealed vessel inside space from the low pressure space of the compression mechanism part via communicating holes 3f and 4f arranged in a frame 14.
