description	The scroll compressor includes a compression unit; a drive shaft which is vertically orientated; a lower bearing arrangement (28) configured to rotatably support the drive shaft; and an oil pump (29) arranged at a lower end of the drive shaft and configured to deliver oil to the compression unit and to the lower bearing arrangement (28). The lower bearing arrangement (28) comprises a radial bearing housing (34) including an inner radial bearing surface (37) surrounding the lower end portion of the drive shaft; upper and lower axial thrust bearings (43, 44) configured to limit an axial movement of the drive shaft; and a pressurized oil chamber (51) fluidly connected to the oil pump (29), the pressurized oil chamber (51) being at least partially delimited by the outer surface of the lower end portion of the drive shaft, the inner radial bearing surface (37) and the upper and lower axial thrust bearings (43, 44).
