たものである。 In the silencer for the hermetic compressor configured in this way, the discharge silencer 17 has first, second and third silencing chambers 24, 2 in the drawn-shaped plastic molded part 21.
5, 26 and the throttle passages 27, 28 are integrally formed, there is no need to separately create the throttle passages 27, 28, which were conventionally formed as separate parts, and the silencing chambers 24, 25, 26 Since the flange portion 29 is integrally formed at the same time as the throttle passages 27 and 28, the flatness of the edge of the plastic molded part 21 and the matching area when joining to the press punched part 15 by brazing increase, thereby increasing the joint strength. Since the discharge muffler 17 can be constructed by only joining two parts, the press punched part 15 and the plastic molded part 21, the discharge muffler 17 which has good performance and is economical can be created with a simple structure. That's what I got.

る。 Further, since the extension part 15a of the press punched part 15 is provided with a discharge hole 23 having a bridging part 22,
As shown in FIG. 5, the opening/closing part 12a of the discharge valve 12
The opening degree of the discharge valve 12 can be regulated by the bridge portion 22 by the thickness of the gasket 14, and there is no need for a special valve holder for the discharge valve 12, reducing the number of parts.

できるものである。 As described above, according to the present invention, a molded part formed with a plurality of recesses and a punched part punched from a plate thicker than the molded part are overlapped to form a plurality of sound-reducing chambers and spaces between the sound-reducing chambers. a discharge muffler formed with a throttle passage communicating with the muffler; a cylinder to which the muffler is attached via a gasket, a discharge valve, a valve seat, and a suction valve provided on the side of the punched part; and a cylinder attached to the die cut part; a suction muffler having a communication pipe made of resin; the punched part is provided with a discharge hole that communicates with the recess of the molded part; the molded part has a flange formed around the recess and joined to the punched part; provided integrally, and
Since the recess of this molded part is separated from the communication pipe,
It is possible to prevent the refrigerant in the communication pipe of the suction muffler from being heated by the high-temperature refrigerant in the discharge muffler chamber, thereby preventing a reduction in refrigerating capacity. Furthermore, the present invention improves sealing performance by increasing the sealing area at the flange of the molded part, and allows the muffler to be molded simply by overlapping two parts, the molded part and the punched part.
