Claim:
1. An air compression apparatus comprising: an air tank; an air compressor configured to: (i) feed compressed air to the air tank by using power of an engine in a loaded running state of the air compressor, and (ii) stop the feeding of the compressed air to the air tank in an unloaded running state of the air compressor; a governor configured to switch the air compressor between the loaded running state and the unloaded running state based on a pneumatic pressure at an inlet side of the governor, the inlet side of the governor receiving compressed air from the air tank, and the received compressed air flowing through the governor; and a regulating valve disposed between the air tank and the governor, the regulating value being configured to be in: (i) an open state when a speed of the engine is below a predetermined threshold value such that the regulating valve relieves a portion of the compressed air flowing from the air tank to the governor, and (ii) a closed state when the speed of the engine exceeds the predetermined threshold value, the pneumatic pressure at the inlet side of the governor being greater when the regulating valve is in the closed state than in the open state, wherein
