Refrigerator compressor

[lethaldriver]

In a refrigerator's compressor there are three pipes. Can anyone tell me what each pipe is for? here is a pic of a compressor.

one in the lower left, lower right and upper right.

It's just that in a car's A/C compressor, there are only two....one inlet and one outlet.

In, out, process.

The "process" tube is used to charge the refrigerant after the assembly is complete, then pinched off and brazed. Cheap but effective.
