) through the discharge port (1a) provided in the discharge valve (13).
is discharged into the space (9a) in the discharge 7 fuller ((υ), and is further discharged into the sealed container (]) through the discharge gas passage (+1) provided in the cylinder (5), and the discharge pipe (1b) is discharged into the refrigeration cycle again.The compressed refrigerant gas is discharged from the compression side (15) of the compression space.
) from the discharge notch (not shown) provided in the end face of the cylinder (5) and the discharge port 04 provided in the lower bearing end plate (8) to the space in the discharge 7 fuller (9) ( 9a)
However, the compressed refrigerant gas passes through the discharge port (14) and instantly pushes the discharge valve (13) down to the discharge muffler (9).
) When it is discharged into the space (9a), it undergoes explosive rapid expansion and excessive pressure waves propagate upstream and downstream, becoming a major source of noise.

により生ずる騒音が大幅に低減されることになる。That is, in the present invention, explosive rapid expansion of compressed refrigerant gas occurs,
Inside the discharge [1 (+4) where pressure waves are formed, the thickness is 20thm to IOQ:tm and the surface is 20μm to 300mm.
A built-in acoustic filter 07) is a spirally wound foil having a protrusion (16) of /lrn. Furthermore, the discharge [1 (1
4) is larger than the inner diameter of the compression side (15) of the compression space in the cylinder (5), and the discharge [(τ4) is eccentric to the compression side Q5 and communicates with it. Further, the inner surface of the lower end of the discharge port (14) has a large diameter to form a stepped portion (+8), and the acoustic filter (17) is placed on this stepped portion (18).
is provided. To be more specific, the acoustic filter (17) is provided within the discharge port 04) while being housed in a filter storage container (19). acoustic filter 0
．． 7) is stored from the lower end of the filter storage container (19), and a lid (20) is provided to prevent the filter storage container (19) from falling. The L end of the lid (2o) and the filter storage container 09) is open and divided into two parts at the center. Since the acoustic filter (17) is built into the discharge port (14) as described above, as shown in FIG.
When compressed refrigerant gas having a large pressure wave passes through the narrow passage (21) of tn, the pressure wave is greatly attenuated in the narrow passage (21), and as a result, the pressure energy is converted into thermal energy and discharged. When the compressed refrigerant gas reaches the space within the muffler, the compressed refrigerant gas does not contain large pressure waves. Therefore, the noise caused by the explosive rapid expansion of the compressed refrigerant gas is significantly reduced.
