Operating Cycle
Power Stroke: As the supply Air/Gas from the Air Timer thru the Pneumatic Drive Cylinder. The Piston - Plunger Assembly is driven down into the fluid Cylinder, Displacing Fluid. The fluid displacement result in an increase in pressure which closes the Suction Valve and opens Discharge Valve . A precise of fluid, corresponding to stroke of the plunger is discharged.
Suction Stroke: When the Air/Gas is exhausted from the top portion of Pneumatic Drive Cylinder through the Air Timer, Air/Gas is then supplied to the bottom portion of the Pneumatic Drive Cylinder in order to return the Piston-plunger to its original position. The piston -Plunger assembly allows the discharge Valve to close and the suction Valve to open. The fluid chamber is then refilled and ready for the power stroke.
