ることを特徴とする圧縮機の脈動低減機構。 A cylinder block having a plurality of cylinder bores formed therein, a plurality of pistons respectively fitted into the cylinder bores, and a plurality of suction holes and discharge holes provided at one end of the cylinder block corresponding to the cylinder bores. The cylinder head is provided at one end of a cylinder block with the valve plate in between, a suction valve that opens and closes the suction hole, a discharge valve that opens and closes the discharge hole, and a cylinder head that is provided at one end of the cylinder block with the valve plate interposed therebetween. In a compressor of a type in which the compressor reciprocates with a predetermined phase difference, the inside of the cylinder head is in communication with a first low pressure chamber that communicates with a suction port formed in the cylinder head, and the suction hole. A second low pressure chamber and a high pressure chamber communicating with the discharge hole and the discharge port formed in the cylinder head are partitioned via a partitioning means, and the first low pressure chamber and the second low pressure chamber are partitioned into the partitioning means. A pulsation reduction mechanism for a compressor, characterized in that a suction communication hole communicating with a chamber is formed, and the suction communication hole is equidistant from at least two suction holes.
