An Air Pressure Amplifier is an air pump that is driven by part of the incoming compressedair supply enabling it to cycle and pump the balance of the supply to a higher outputpressure. Pressure is generated by the use of a differential area piston assembly (Fig 1).Low pressure air applied to a large area creates high pressure air on the small area. Cyclingis achieved through the use of two pilot valves that alternately pilot and vent the largearea end of an unbalanced cycling spool. The small area end of the cycling spool uses apermanent air spring. This unbalanced cycling spool ensures that the air amplifier cycles ondemand.
