Operation

POWER STROKE:
As the supply air/gas from the CONTROLLER-RELAY enters the PNEUMATIC DRIVE CYLINDER thru the POWER STROKE PORT, the PISTON-PLUNGER ASSEMBLY is driven down into the FLUID CYLINDER, displacing fluid. The fluid displacement results in an increase in pressure which closes the SUCTION CHECK VALVE and opens the DISCHARGE CHECK VALVE. A precise amount of fluid, corresponding to the stroke of the plunger, is discharged.

SUCTION STROKE:
When the air/gas is exhausted from the top portion of the PNEUMATIC DRIVE CYLINDER through the CONTROLLER-RELAY, 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 drop in pressure caused by the retraction of the PISTON-PLUNGER assembly allows the DISCHARGE CHECK VALVE to close, and the SUCTION CHECK VALVE to open. The FLUID CHAMBER is then refilled and ready for the POWER STROKE.
