Abstract: This scroll compressor includes a scroll compression unit including a first fixed scroll including a first fixed base plate and a first fixed spiral wrap, an orbiting scroll arrangement (7) including a first orbiting spiral wrap (14), the first fixed spiral wrap and the first orbiting spiral wrap (14) forming a plurality of first compression chambers. The scroll compressor further includes a refrigerant suction part suitable for supplying the scroll compression unit with refrigerant to be compressed. The orbiting scroll arrangement (7) further includes a first orbiting guiding portion (21) extending from an outer end portion of the first orbiting spiral wrap (14) and configured to guide, in use, at least a part of the refrigerant supplied to the scroll compression unit towards the first compression chambers.

Abstract: The scroll compressor (1) includes an orbiting scroll arrangement (7), and a drive shaft (18) configured to drive the orbiting scroll arrangement (7) in an orbital movement, the drive shaft (18) including a lubrication channel (32) and a first lubrication hole (35) fluidly connected to the lubrication channel (32) and emerging in an outer wall of the drive shaft (18). The scroll compressor (1) further includes a first and a second bearings (38, 39) axially offset along a rotation axis of the drive shaft (18) and each configured to engage the drive shaft (18). The first and second bearings (38, 39) and the drive shaft (18) partially define a first annular gap (44) in which emerges the first lubrication hole (35). The first bearing (38) and the drive shaft (18) define a first oil recess fluidly connected to the first annular gap (44), and the second bearing (39) and the drive shaft (18) define a second oil recess fluidly connected to the first annular gap (44).

Abstract: This scroll compressor (2) includes a first and second fixed scrolls (4, 5) comprising first and second fixed spiral wraps (9, 12), an orbiting scroll arrangement (7) comprising first and second orbiting spiral wraps (14, 15), the first fixed spiral wrap (9) and the first orbiting spiral wrap (14) forming a plurality of first compression chambers (16) and the second fixed spiral wrap (5) and the second orbiting spiral wrap (15) forming a plurality of second compression chambers (17). The scroll compressor further includes a drive shaft (23) adapted for driving the orbiting scroll arrangement (7) in an orbital movement, and a driving motor (24) arranged for driving in rotation the drive shaft (23) about a rotation axis, the driving motor (24) being located nearby the first fixed scroll (4). The first fixed scroll (4) includes at least one first discharge passage (21) arranged to conduct the refrigerant compressed in the first compression chambers (16) towards the driving motor (24).
