The low pressure gas of the refrigerant is introduced into the compression chambers 8a and 8b via a and 10b. In this embodiment, expanded tube portions 14a and 14 formed in the sealed container side portions 11a2 and llb2 are
Inhalation to b? When fitting the 7-side suction pipes 11a, 1lb2, positional deviations caused by variations in the dimensional accuracy of each part can be corrected by applying a slight force to the closed container side parts 11a2, 1lb2. The two suction muffler side portions 11a, 1lb smoothly connect to the expanded portion 14a,
14b. Since these fitting parts form joint parts 12e and 12f by l1 contact etc., usually 0.05II
Since only a gap of about 0.2 m is formed, it is necessary to correct the positional deviation as described above. Therefore, if it is not possible to easily correct misalignment, it is necessary to strictly control the accuracy of each part, and the accuracy of processing and assembly.
This conventionally results in high costs, but in this embodiment,
Perhaps because the suction tube is made of copper and has a thin wall, the above-mentioned positional deviation can be easily corrected with a small amount of force. The configuration of this embodiment other than the above is the same as the conventional one shown in FIG. FIG. 2 shows another embodiment of the present invention, and the same reference numerals as in FIGS. 1 and 3 in FIG. 2 indicate the same or corresponding parts. Second
The embodiment shown in the figure has a suction w protruding below the suction muffler 1.
Intake muffler side portions 11a,,llb, of lla,llb,
The only difference from the one shown in FIG. 1 is that expanded tube portions 14a and 14b are provided at the lower end, and the upper ends of the closed container side portions 11a2 and llb2 are fitted and connected to these, and this embodiment also has the same structure as that shown in FIG. The same effect as shown is obtained.
