    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).

    Abstract: The refrigeration compressor according to the invention comprises a sealed enclosure containing a compression stage (7) and provide with a refrigerant inlet and outlet (6, 18), the compressor being configured such that under usage conditions, a flow of refrigerant circulates through the refrigerant inlet, the compression stage, and the refrigerant outlet. The compressor has an oil pan (24) and oil recirculation means arranged to orient the oil contained in the oil pan into the flow of refrigerant when the oil in the oil pan exceeds a predetermined oil level (34). The recirculation means include a recirculation line (35) housed in the sealed enclosure and comprising an inlet port (36) situated at a height substantially corresponding to the predetermined oil level, an outlet port (37) emerging in the refrigerant flow, and an intermediate part (38) connecting the inlet and outlet ports. The intermediate part (38) includes a first portion (38a) extending below the predetermined oil level (34).
