Abstract

A compressor having a compression element including a cylinder having a compression space; a suction port and a discharge port; 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 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. The hardness of the upper surface of the compression member may be higher than that of a discharge member as a receiving surface of the top dead center and lower than that of the vane.
