Abstract

PURPOSE:To reduce the oil supply quantity and to improve feeding and lubricating effects by utilizing a pumping action produced by sliding of a vane to supply oil in a back pressure portion of the vane to the respective oil feeding grooves of upper and lower bearings. CONSTITUTION:When an electrically driven element 26 is started, a rotor shaft 32 connected to a rotor 30 is rotated and a vane 34 is brought into contact with the inner surface of a cylinder 31 to slide in a vane groove 33. Then, refrigerant gas flowing from an intake hole 45 into the cylinder 31 is compressed to push up a discharge valve 48, so that the gas is discharged from a discharge hole 47. The refrigerant gas flows in a closed receptacle 28 through a discharge hole 51, and then discharged to the outside through a discharge pipe 53. At this time, the oil which flows into an oil groove 38 through an oil feed hole 37 of a lower bearing 36 is introduced into the vane groove 33. By pumping action caused by sliding of the vane 34, oil is supplied to respective grooves 41 of upper and lower bearings 35, 36.
