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).
