The melting point of the above bronze brazing filler metal is the melting point of copper (approximately 1080
The temperature difference between the two temperatures is only about 40℃ to 50℃. For this reason, when melting bronze brazing filler metal, it must be melted at a temperature that will not cause the copper pipe to deteriorate, i.e., at a temperature slightly higher than the melting point of the bronze brazing filler metal.The melted bronze brazing filler metal has a high surface tension and has poor flowability. Bad,
There were cases where the bronze brazing filler metal did not flow evenly between the collar 3 and the copper pipe 4. If the bronze brazing filler metal does not flow evenly, use collar 3 and copper pipe 4.
There was a possibility that the refrigerant gas inside the case 1 would leak due to poor sealing performance between the case 1 and the case 1.

The above purpose is to provide a compression mechanism, a case housing the compression mechanism, a copper pipe for silver brazing the copper piping of the refrigeration cycle, and a collar interposed between the case and the pipe. In the compressor, the collar has a cylindrical part to which the pipe is brazed, and the pipe is connected to the compression mechanism part and the case, wherein the collar is continuous with an inner surface of the cylindrical part. This is achieved by providing a compressor having a sloped portion, a groove for flowing the brazing material on the inner surface of the cylindrical portion, and the pipe and the collar being brazed with bronze.

A bronze brazing filler metal 14b is poured between the collar 13 and the copper pipe 14. This bronze brazing material 14b is poured into a groove 13d provided in the cylindrical portion 13a of the collar 13. Since the bronze brazing material poured into the groove 13d flows in the groove 13d as shown by the arrow, the bronze brazing material flows evenly between the collar 13 and the copper pipe 14. The iron bushing 15 has an outer diameter portion 15a that is inserted into the suction port 12a, and a shoulder portion 15 that bites into a part of the stepped portion 14c of the copper pipe 14.
