Abstract: PURPOSE: A compressor is provided to reduce refrigerant discharge pulsation in a process of compressing/discharging refrigerant and to promote compact structure by adopting pulsation reducing structure without increasing the volume of a compressor. CONSTITUTION: Refrigerant is compressed by a piston(2) and discharged to a discharge chamber(42) through a discharge hole(512) of a valve plate(51) from a bore. The refrigerant is diffused to a discharge pipe(47) with time difference through pulsation reducing structure consisting of at least two discharge ports(471,472) having different distances to the discharge hole. The pulsation frequency is increased in proportion to the number of discharge ports connecting the discharge chamber with the discharge pipe, but pulsation is reduced remarkably. Thereby, drive noise proportional to size of pulsation is reduced. In addition, the drive noise of a compressor is reduced more if each refrigerant flow is joined at the discharge pipe with phase difference of pulsation.
