ABSTRACT:
A compressed air system includes an air compressor the inlet of which is communicated to the vehicle engine turbocharger. The outlet of the air compressor is communicated through an air dryer to a storage reservoir. A governor is responsive to the pressure level in the reservoir to generate an unloading signal unloading the air compressor when the pressure in the reservoir attains a predetermined value. The unloading signal is also communicated through a control valve to purge the air dryer during compressor unloading. The control valve closes communication between the governor and the air dryer to trap a predetermined pressure level in the purge volume of the air dryer to prevent the air dryer from purging to atmospheric pressure. Accordingly, a predetermined air pressure level is maintained in the purge volume, so that the outlet of the turbocharger can never be communicated to atmospheric pressure.
