ABSTRACT:
A pneumatic fluid dispenser has an electromechanical actuator that is supported by a dispenser body and operable to move a mechanical stop in the dispenser body. A drive piston also mounted in the dispenser body is powered by pressurized air and is movable into contact with the stop. Thus, the stop limits a displacement of the drive piston and hence controls a volume of fluid dispensed by the pneumatic fluid dispenser.
