Which device controls when air is pumped into the air tanks?

Explanation:
The air compressor governor is the device that controls when air is pumped into the air tanks. It monitors the system pressure and turns the compressor on and off to keep pressure within a safe range. When the pressure drops to the low cut-in point, the governor starts the compressor; when it reaches the high cut-out point, it stops the compressor. This keeps enough air ready for braking and other systems without over-pressurizing the tanks. The brake pedal, the service brake chamber, and the emergency valve all deal with braking actions or safety responses, not with regulating when air is added to the tanks.
