Governor Air Compressor Air Brakes

R and M Diesel Truck Air Brake Compressor Governor Service
Short drive from down town Little Rock, Arkansas
Close to I-30 and I-530.

The Air Compressor Governor controls when the air compressor pumps air into the storage tanks.

Air compressors are designed to run whenever the engine is running. As a result, they are able to produce much more air than is needed by the brake system.

To prevent the compressor from producing too much compressed airĀ  and blowing a component out and to reduce the load on the engine, a governor is used in the air brake system.
When air-pressure is high enough in the system, the governor causes the compressor to stop pumping air (cut-out).
When the air-pressure drops to a certain point, the governor will cause the compressor to start pumping air again (cut-in).

Compressed air can be hazardous

Key points to remember.
Compressed air is a form of stored energy that can be hazardous.
Air compressors compress air by forcing it into a smaller space.
Air compressors are powered directly by the engine or by using belts and pulleys.
Air compressors are mounted directly on the engine or by brackets and fasteners.
The governor controls the air compressor cut-in and cut-out pressure.
The operating pressure range for vehicle air brake systems must be between 80 psi and 135 psi. It is unsafe to drive a vehicle when the air pressure is outside the normal operating range.

Ā Compressed air is stored in the vehicleā€™s supply or “wet” tank and the dual service (primary and secondary) air tanks. To prevent too much moisture and oil from collecting, the air tanks must be drained regularly.
Air pressure gauges indicate air pressure in the vehicleā€™s dual service (primary and secondary) air tanks.
Safety valves prevent over-pressure of the air brake system.
Low air pressure warning devices give drivers a visual, and sometimes audible, warning that air-pressure is dangerously low.
An air dryer removes moisture from the air brake system and expels it when the compressor reaches cut-out pressure.
An alcohol evaporator adds alcohol vapor to the air brake system to help prevent moisture in the system from freezing.Ā
