    Abstract: A scroll compressor including a compression unit includes a first non-orbiting scroll having a receiving cavity and an orbiting scroll arrangement. The compression unit further includes a refrigerant suction part suitable for supplying the compression unit with a refrigerant flow, and a first anti-rotation device located in the receiving cavity and configured to prevent rotation of the orbiting scroll arrangement with respect to the first fixed non-orbiting scroll. The compression unit further includes an oil discharge device including an oil discharge passage, the oil discharge passage includes an oil inlet fluidly connected to the receiving cavity and at least one oil discharge outlet located in a refrigerant flow path and configured to supply the refrigerant flow with oil from the receiving cavity.

    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).
