に排出される。Further, 16 is a container suction port, 17 is a lubricating oil, and 18 is a base spring. When the rotor 3 of the electric motor rotates, the directly connected crankshaft 4 rotates, and the piston 8 reciprocates within the cylinder chamber 9 via the rod 6 to compress the refrigerant. The flow path of the refrigerant gas enters the container space 11 through the container suction port J6, and enters into the container space 11 through the suction port 12 through the suction silencer 13. After passing through the head cover 14 and the cylinder chamber 9, it passes through the head cover 14, a discharge silencer (not shown), and a discharge pipe I5, and is discharged to the outside of the closed container.

った。The hermetic refrigerant compressor configured in this way has a container suction port I6.
After the refrigerant is diffused into the container space 11, it is throttled by the lower suction silencer with a small diameter, so the flow resistance of expanding and contracting flows becomes large, and it takes considerable power to satisfy the desired pressure conditions. This method has the disadvantage of requiring an extra 1.

Since the suction refrigerant is directly connected to the suction silencer 21 by a metal bellows 23, the suction refrigerant does not need to be ejected once into the container space II, but directly flows into the suction silencer 21, which greatly reduces the flow resistance and improves the efficiency of the compressor. It is something. Hermetic compressors typically have a joint 24 that connects the lid chamber 2.
5 and a bottom chamber 26, a method that is easy to assemble is required to connect the suction port 22 and the container suction port 20 when assembling the compressor. In the case of the metal bellows of the present invention, the metal bellows 23 is positioned and fixed on the upper part of the suction silencer 21 before the lid chamber 25 is covered, and the upper end of the metal bellows 23 is positioned at the suction port 22 when the lid chamber is connected to the bottom chamber. By designing it in such a way that it can be easily assembled. The metal bellows and the suction port do not need to be completely sealed, and the container suction port 1
The function may be such that most of the refrigerant flowing in from 6 flows into the suction silencer 21.

。As described above, the present invention uses the container suction port 20 as a suction flow path.
The suction port 22 of the suction silencer 21 is connected to the metal bellows 23.
It is possible to improve the efficiency of the compressor with a structure in which the compressor is directly connected to the compressor.
