Abstract

PURPOSE: To make it possible to provide good lubrication on a vane by forming a through pore on the outer end of a guide channel which is provided on a cylinder and in which a vane making slidable contact with the peripheral side of an eccentric roller is engagedly fitted, and also forming an oil supply passage for connecting the inner circumference portion of the roller with the inner space of a closed case.
CONSTITUTION: If a roller 2 is eccentrically turned within a cylinder 1, each capacity of a suction chamber and a compression chamber partitioned by a vane 6 located in a radial guide channel 1a formed on the cylinder 1 and making slidable contact with the peripheral side of this roller 2 varies in sequence, then fluid compressed in the compression chamber is discharged from a discharge pipe 15. In such a compressor as mentioned above is formed a through pore 1b vertically penetrating the cylinder 1 at the outer end of the guide channel 1a. And an upper end plate 8 is provided with an oil supply passage 12 having its one end communicated with the internal circumference portion of the roller 2 through a pore 12a and the other end communicated with the inside of a closed case 10 through an oil supply pore 12b which has an opening 12c provided opposite to the through pore 1b.
