ABSTRACT:
Fluid to be dispensed is delivered under pressure to a dispensing nozzle by way of an infinitely variable valve which is disposed in sufficiently close proximity to the nozzle that very little fluid pressure drop takes place in the region between the valve and the nozzle. A parameter correlated to the rate of flow of fluid discharged from the nozzle is sensed between the valve and the nozzle to generate a flow rate signal from which a control signal is derived by comparing the flow rate signal with a signal representing a desired rate of flow. Where the nozzle is to be moved relative a workpiece for dispensing fluid material thereon, the latter signal may be derived from a signal correlated to the speed of relative movement between the nozzle and the workpiece such as a tool speed signal from the robot.
