What is the small thin tube on the valve of a reciprocating piston compressor used for?

Lubricating oil, or an air seal? Nitrogen compressor
A pneumatic valve, as the name suggests, is a valve that operates using an air source; these small air pipes are likely to contain compressed air, that is, the air supply pipeline
These small pipelines should contain instrument air; the component located above the air valve is actually a pneumatic actuator, which controls the opening of the air valve through its actions in order to regulate the amount of air supplied to the compressor
Thank you. I checked again just now; it seems to be a unloader that uses instrument air to control the opening degree of the compressor valves, thereby regulating the load
The upper part is the instrument air line, and the lower part is the relief valve leakage port
It’s the air duct of the unloader, used to control the opening degree of the air valve
I discovered for the first time that there is also a nitrogen compressor. What is its working principle?
Unloader, used to adjust the work done by the compressor; its setting should be in the form of 0% 50% 75% 100%
Unloader: load reduction in windy conditions, loading in calm conditions
These small pipelines should be instrument air
