What does the air compressor governor primarily regulate?

  1. The speed of the air compressor

  2. Brake pressure

  3. The pumping of air into the storage tanks

  4. The amount of air released from tanks

The correct answer is: The pumping of air into the storage tanks

The air compressor governor is a critical component of the air brake system, as it ensures that the air compressor functions effectively and maintains the appropriate air pressure necessary for the braking system to operate. Its primary role is to regulate the pumping of air into the storage tanks. When the air pressure in the storage tanks falls below a certain threshold, the governor activates the compressor to increase the pressure. Once the pressure reaches the preset levels, the governor disengages the compressor, preventing over-pressurization. This cycle ensures a consistent supply of compressed air, which is essential for the operation of air brakes in commercial vehicles. By regulating the pumping action, the governor helps maintain the efficiency and reliability of the air brake system.
