Abstract: The oil injection device according to the invention includes an oil pump designed to be rotationally coupled to the electric motor of a compressor and including inlet and outlet ports, an oil injection duct connected to the first outlet port and designed to supply a compression stage of the compressor with oil, and an oil return duct connected to the first outlet port and designed to return the oil into an oil sump of the compressor. The pressure losses in the oil injection duct are primarily singular pressure losses proportional to the square of the oil flow rate passing through the oil injection duct. The pressure losses in the oil return duct are primarily pressure losses due to friction proportional to the oil flow rate passing through the oil return duct.

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).
