Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2018/212076
Kind Code:
A1
Abstract:
This scroll compressor is provided with a fixed scroll (12) and a movable scroll (11), changes the capacity of a working chamber by orbital motion of the movable scroll so as to cause a refrigerant to be suctioned into the working chamber from a suction chamber (40), to be compressed, and to be discharged as a high-pressure refrigerant out of the working chamber. The scroll compressor is further provided with: a back-pressure chamber formation part (29) which forms a back-pressure chamber (50) that stores the high-pressure refrigerant discharged from the working chamber so as to generate a refrigerant pressure for pressing the movable scroll on the fixed scroll; and a balancer (254) which is disposed within the back-pressure chamber and which is rotated when being driven by a rotary shaft, so as to lessen weight imbalance generated in the rotary shaft on the basis of the movable scroll when the movable scroll undergoes orbital motion. The back-pressure formation chamber is provided with a discharge port (70) that connects the suction chamber and a radially outer side of the back-pressure chamber when the axial line (S) of the rotary shaft is the center and that discharges a liquid-phase refrigerant from the back-pressure chamber to the suction chamber when the liquid-phase refrigerant coming out of the working chamber enters the back-pressure chamber.
