PROBLEM TO BE SOLVED: To improve the efficiency by reducing suction loss by preventing the interference of pressure pulsation generated by one of the cylinders disturbing suction to an operating chamber of the other cylinder. SOLUTION: A compressing mechanism part is provided with a plurality of cylinders 6a, 6b, each cylinder 6a, 6b is provided with a plurality of operating chambers 51, 52 defined by a partition plate 50 and a pair of end plates 5, 8. A crank shaft 3 is provided with a plurality of crank pins 13, 14 of different phases. A suction chamber 51 is provided with suction ports 20a, 20b communicated to suction pipes 19a, 19b through a suction channel. The suction channel has a channel part 30 communicating a channel part of each cylinder 6a, and channel parts 23a, 23b of the cylinder enlarged to both end faces of the cylinder.
