  • SCROLL COMPRESSOR PROVIDED WITH A FLUID DEFLECTING AND DIVIDING DEVICE
    Publication number: 20180355869
    Abstract: The scroll compressor (2) includes an outer shell (4); a refrigerant suction inlet (7) formed in the outer shell (4) and configured to supply the scroll compressor (2) with refrigerant to be compressed; a compression unit (11) configured to compress refrigerant; a driving motor (21) configured to drive the compression unit (11) via a drive shaft (19); a fluid deflecting and dividing device (35) configured to divide a refrigerant suction flow entering the scroll compressor (2) through the refrigerant suction inlet (7) at least into a first flow (F1) and a second flow (F2). The fluid deflecting and dividing device (35) includes a first end (37) facing the refrigerant suction inlet (7) and a second end (38) which is closer to the compression unit (11) than the first end (37), the fluid deflecting and dividing device (35) being configured to guide the first flow (F1) towards the compression unit (11) and to guide the second flow (F2) towards the driving motor (21).
