What component controls when the air compressor pumps air into the air storage tanks?

• A. Governor
• B. Safety relief valve
• C. Temperature gauge
• D. Pressure switch

Answer: (A)

The governor regulates when the air compressor pumps air into the storage tanks. It senses the tank pressure and automatically starts the compressor when pressure falls to the cut-in level and stops (or unloads) it when pressure reaches the cut-out level. This keeps the system within a safe, efficient pressure range without the operator having to manually control the pump. The safety relief valve is a safety device to vent air if pressure becomes too high, not the normal cycling mechanism. A temperature gauge just shows how hot the compressor is, and a pressure switch may be used for other signaling in some systems but does not routinely control the compressor’s on/off cycling like the governor does.
