Description

A compressor according to the present invention is provided in a compression unit, an electric motor unit that is connected to the compression unit via a main shaft, drives the compression unit, a sealed container that houses the compression unit and the electric motor unit, and a discharge port of the compression unit. It is to reduce the discharge fluid sound of the refrigerant discharged from the discharge port, and a Mute device that drained the refrigerant into the hermetic container from the outlet, provided the insertion tube to the outlet of the silenced device Is.

In the present invention, and an insertion tube provided the outlet of the silenced device. For this reason, the discharge fluid sound at the time of a refrigerant | coolant being discharged from a compression part can be reduced conventionally compared with the resonance effect of an insertion pipe.
