Patent ID: 7762798

Claim:
A compressor comprising: a compression element comprising a cylinder in which a compression space is constituted; a suction port and a discharge port which communicate with the compression space in the cylinder; a compression member whose one surface crossing an axial direction of a rotary shaft is inclined continuously between a top dead center and a bottom dead center and which is disposed in the cylinder to be rotated by the rotary shaft and which compresses a fluid sucked from the suction port to discharge the fluid from the discharge port; and a vane which is disposed between the suction port and the discharge port to abut on one surface of the compression member and which partitions the compression space in the cylinder into a low pressure chamber and a high pressure chamber, wherein hardness of one surface of the compression member is set to be higher than that of a receiving surface of the top dead center and lower than that of the vane.
