Abstract
A swash plate type compressor used for the air conditioner of an automobile is presented. The compressor has a structure where pulsation pressure caused when refrigerants are compressed and discharged is reduced, thereby permitting noise at the time of driving to be substantially reduced. The compressor can embody the structure by distributing and discharging refrigerant that has been compressed by a plurality of pistons and discharged from a plurality of bores into at least two discharge holes, wherein a frequency of the pulsation pressure is increased in proportion to the number of the discharge holes, but the strength of the pulsation pressure is decreased in inverse proportion to the number of discharge holes. Therefore, the driving noise of the compressor that is formed in proportion to the strength of the pulsation pressure is considerably decreased.
