A discharge muffler main body C equipped with a reduction mechanism is provided, and a condenser (

ある。However, since the discharge muffler of the hermetic compressor described above occupies a large amount of space because it is installed through the discharge pipe, it is not only limited in the installation space but also outside the case body a. Since it is attached to the container, it becomes a hindrance during transportation and also complicates assembly and configuration.

になる等の雛点がある。However, the above-mentioned hermetic compressor has a high temperature that is pulsatingly discharged to the discharge muffler 2 provided on the outer periphery of the case body l.
After the high-pressure refrigerant flows in, it flows uniformly outward and flows out from the discharge pipe 2, which increases the temperature of the entire hermetic compressor, which reduces the compression efficiency of the refrigerant. This not only reduces the quality of the case, but also makes machining of the case body difficult.
