Abstract
In a refrigerant gas compressor wherein a refrigerant gas compressed in a cylinder bore is discharged out therefrom into a discharge chamber through a discharge port, there is provided a plurality of attenuating cavities in the discharge chamber each located in such facing relation to the discharge port that the refrigerant gas discharged through said discharge port is introduced into said cavity.
Claims3
In a refrigerant gas compressor having formed therein a plurality of cylinder bores, a discharge chamber communicable with each of said cylinder bores through a discharge port for receiving a refrigerant gas compressed in said each cylinder bore and then discharged out therefrom through said discharge port, and an exit port having an opening formed in said discharge chamber for allowing the refrigerant gas out of said compressor through said exit port, a device for attenuating pulsations of the refrigerant gas in said discharge chamber, comprising a plurality of cavities formed with different depths in said discharge chamber in communication therewith, each of said cavities being located in such facing relation to said discharge port that the refrigerant gas discharged through said discharge port is introduced into said cavity, and the area of said each cavity in transverse cross-section being larger than that of said discharge port.
