PROBLEM TO BE SOLVED: To provide a compressor capable of smoothly supplying an oil to sliding parts. SOLUTION: This compressor comprises a drive element 2 stored in a closed container 1 and a compression element 3 driven by the rotating shaft 5 of the drive element 2. The compression element 3 comprises a cylinder 78 in which a compression space 21 is formed, a suction port 27 and a discharge port 28 communicating with the compression space 21 in the cylinder 78, the compression member 9 having an upper surface 33 (one surface) crossing the axial direction of the rotating shaft 5 continuously tilted between a top dead center 33A and a bottom dead center 33B, disposed in the cylinder 8 and rotated, and compressing a fluid sucked from the suction port 27 and discharging it from the discharge port 28 into the closed container 1, and a vane 11 disposed between the suction port 27 and the discharge port 28, abutting on the upper surface 33 of the compression member 9, and dividing the compression space 21 in the cylinder 8 into a low pressure chamber LR and a high pressure chamber HR. The back pressure of the vane 11 is set lower than a pressure in the closed container 1. COPYRIGHT: (C)2006,JPO&NCIPI
