Fridge compressor teardown reveals engineering compromises

  > Probably one of the most reliable devices you will have in your house is the refrigerator, as its compressor has the minimum of moving parts and carries its own lubrication. Most compressors (if not all) self lubricate since they compress in a closed loop. I've recently become a home owner and had to replace the compressor in my A/C unit (as well as some other parts) and it is truly a marvel of engineering.
