This section has the description and the service pro- cedures for the air compressor.
The air compressor maintains the supply of air for the brake system. The compressor is driven by the engine and can have air or water cooling. The compressor is lubricated with oil from the engine.
The air compressor runs all the time the engine is running. The compression of air is controlled by the governor. As the piston moves down, air enters the compressor through the inlet valve. As the piston moves up, the air in the cylinder is compressed. The compressed air leaves the compressor through the outlet valve. The air then enters the air tank.
When the pressure of the air reaches the maximum setting of the governor, the governor opens. While the governor is open, air from the air tank returns to the compressor through the governor. The air from the air tank enters the chamber for the release plung- ers. The plungers move up and hold the inlet valves off of their seats. Now, the air is transferred between the cylinders. There is no compression of the air at this time. When the pressure of the air in the tank reaches the minimum setting of the governor, the gov- ernor closes. The air is released from the chambers.
