Abstract
There is provided an efficient compressor which is simple in structure and small in torque fluctuation. The compressor comprises a compression element which comprises a cylinder having a compression space formed therein, a suction port and a discharge port which communicate with the compression space in the cylinder, a compression member which comprises continuous thick and thin parts, one surface of which inclines, which is arranged in the cylinder to rotate, and which compresses fluids sucked through the suction port and discharges the compressed fluids through the discharge port, and a vane which is arranged between the suction port and the discharge port to abut on one surface of the compression member, and which partitions the compression space of the cylinder into a low pressure chamber and a high pressure chamber.
