What role does the governor play in an air compressor system?

The governor's role in an air compressor system is primarily to regulate system air pressure by cycling the compressor. This function is crucial because it helps maintain consistent operating pressure within the system, ensuring optimal performance. The governor detects variations in pressure and activates or deactivates the compressor accordingly to keep the pressure within the desired range.

By cycling the compressor on and off, the governor prevents excessive pressure build-up which can damage the system or lead to inefficient operation. This automatic regulation is essential for maintaining efficiency in pneumatic systems, allowing them to function effectively without manual intervention. Thus, the governor plays a vital role in the overall reliability and efficiency of the air compressor system.
