Abstract: A low power rotation compressor includes a base, a rotation disk, a piston structure, and a casing. When the rotation disk is rotated, the piston structure is moved by rotation of the rotation disk, to co-operate with the cylinder structure and the slide-way, to press the air contained in the air collection container of the casing into the pressure storage container of the casing, thereby producing a required pressure simultaneously. Thus, the low power rotation compressor may use a low power motor to obtain a higher pressure and a higher air exhaust rate, thereby increasing the efficiency and decreasing the cost.
