Sensor/thermal bulb from a capillary tube. Likely from a refrigerator.
Alright, thank you! 17 years of wondering are finally over.
You should still keep your piece of trash just for the memories, now.
Of course! It is my most dearest piece of trash.
What does it do?
From a quick search, it is used to control the flow of refrigerant based on its temperature. The tube deforms based on how hot or cold the refrigerant is, and there are contacts on the tube to switches that permit or resrrict coolant flow
In other words, it's a simple thermostat
Wow, that’s pretty clever.
Physics, yo
Just to add my 2 cents, it's more likely a filter/drier from a refrigerator. Those are much more common, even though a sensor/thermal bulb looks very similar.
