Abstract: The scroll compressor (2) comprises a hermetic enclosure (3) comprising an outer shell (4); a compression unit (11) arranged within the hermetic enclosure (3); an electric motor (21) configured to drive the compression unit (11), the electric motor (21) including a rotor (22) and a stator (23); and an inner shell (26) in which the electric motor (21) is arranged. A baffle (34) is arranged inside the inner shell (26) at a stator end winding (25) of the electric motor (21), the baffle (34) comprising deflecting means configured to deflect at least a part of a main refrigerant flow, flowing inside the inner shell (26), towards said stator end winding (25).

Abstract: The scroll compressor comprises a fixed scroll element comprising a fixed end plate (13) and a fixed spiral wrap (14); an orbiting scroll element comprising an orbiting end plate and an orbiting spiral wrap (16), the fixed and orbiting spiral wraps (14, 16) being intermeshed with each other to define pairs of compression pockets, a radial inner pair of compression pockets comprising a direct pocket (17.1) and an indirect pocket (17.2); a central main discharge port (18) formed in the fixed end plate (13) and configured to communicate the direct pocket (17.1) with a discharge pressure volume; and an auxiliary discharge port (26) formed in the fixed end plate (13) at a position close to an outer wall side (14.2) of the fixed spiral wrap (14) and adjacent the inner end (14.4) of the fixed spiral wrap (14). The auxiliary discharge port (26), during orbiting movement of the orbiting scroll element (12), is at least partially uncovered by the orbiting spiral wrap (16) to communicate the indirect pocket (17.2) with the discharge pressure volume.

Abstract: The scroll compressor (1) includes a compressor shell (2) having a discharge outlet (4); a fixed scroll (7) arranged within the compressor shell (2) and including a fixed base plate (11) and a discharge passage (16) which is formed in the fixed base plate (11) and which is provided with a discharge port (17) emerging into a discharge pressure volume (18) at least partially defined by the compressor shell (2) and the fixed scroll (7); and a deflector (29) arranged in the discharge pressure volume (18), the deflector (29) covering the discharge port (17) and at least partially delimiting a discharge opening (31) facing the discharge outlet (4) of the compressor shell (2), the deflector (29) being configured to force a compressed refrigerant gas flow emerging from the discharge port (17) to smoothly shift from an axial direction to a radial direction and being configured to direct said compressed refrigerant gas flow towards the discharge outlet (4).
