Abstract: The discharge valve arrangement (17) includes a valve plate (18) including a discharge passage (22) and a valve seat (23) surrounding the discharge passage (22); a valve housing (24) being secured to the valve plate (18) and including a bottom portion (25) facing away from the valve plate (18), a sidewall (26) extending from the bottom portion (25) and towards the valve plate (18), and a discharge opening (28) formed in the sidewall (26); a valve member (31) displaceable between a closed position in which the valve member (31) closes the discharge passage (22) and an open position in which the valve member (31) opens the discharge passage (22). The valve housing (24) includes a gas damping chamber defined by the bottom portion (25) and the sidewall (26) and being configured to accommodate the valve member (31) in the open position; and an exhaust opening (37) formed in the bottom portion (25) and emerging in the gas damping chamber.

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).
