摘要： A multi-cylinder compressor includes a valve plate having a plurality of cylinder suction ports formed therethrough, and a plurality of cylinder bores centered on an arc having a radius (R). The cylinder bores are substantially equally spaced from each other, and have a diameter (D). The compressor also includes a suction chamber having a substantially annular shape and adapted to be in fluid communication with each of the cylinder bores via the suction ports. Moreover, a center of a first of the suction ports is radially offset in a predetermined direction from a center of a predetermined suction port by a first angle, in which the predetermined suction port has a diameter (d), and the first angle equals {[(360°/N)·([N−1]−n)]+X°}. In this formula, N is a number of the suction ports formed through the valve plate, n is a number of the suction ports positioned between the first suction port and the predetermined suction port in a direction opposite to the predetermined direction, and X° is a predetermined angle which is less than or equal to {(sin−1[(D−d)/2·R])·57.3°/Radian} and greater than or equal to −{(sin−1[(D−d)/2·R]·57.3°/Radian}, and which is not equal to 0°.
