Q

The candidate should describe the basic principles of the air production system.

A

Air is drawn by the compressor which then passes it to the engine stop cylinder and throttle air actuator. Then on to the main reservoir tank. Pressure is controlled by a compressor governor, which dumps any excess air to atmosphere via the purge valve. Upon leaving the main reservoir tank air is passed to the distribution system via M.R.P.I.C.
