When the pressure in the air receiver reaches the pre-set
maximum pressure, the contacts as well as pressure release
valve (2) are opened. The motor stops, the air at the delivery
side of the compressor is vented to atmosphere and check valve
(CV) closes to prevent venting of the receiver.
When the pressure in the air receiver decreases to the pre-set
minimum pressure, the contacts of the air pressure switch close
and pressure release valve (2) closes. The motor restarts and
compressed air is supplied to the receiver again.
