PURPOSE:To smooth lubrication with a simple constitution by a method wherein a pump mechanism, whose movable part is operated in cooperating with the revolving motion of movable element of the compression mechanism, is provided on the way of an oil path, whose one end is communicated with the inside of lubricating oil and the other side thereof is communicated with the entrance port of a guide path to respective sliding parts. CONSTITUTION:When the movable element 11 is revolved, the movable ring 35 of an OLdham mechanism 31 reciprocates into left and right directions utilizing keys 33a, 33b as a guiding mechanism. As a result, the rod 56 of the pump mechanism 53, which is abutted against the movable ring 35, reciprocates also to suck or discharge the lubricating oil 5 from or into a cylinder 55 through a fluid diode 58. The discharged lubricating oil 5 is supplied to a lubricating oil supplying port 51 through a pipeline 52, flows down through a groove 66 and lubricates the sliding part between the inner peripheral surface of a bearing hole 41 and a small shaft 21. Further, the lubricating oil 5 lubricates the OLdham mechanism 31 and respective sliding parts successively. According to this method, smoothening of supply of lubricating oil may be effected with a very simple constitution, especially by the pump mechanism utilizing no electric power.
