Abstract: Described herein is the combination of a fluid pulse generator for generating a sequence of periodic fluid pulses of substantially equal fluid volume in response to a corresponding sequence of periodic digital signals, and a fluid pulse smoother which receives the fluid pulses from the generator and integrates or smooths those fluid pulses to provide a continuous flow of fluid whose volume and rate of flow correspond to the volume and rate of flow of fluid associated with the pulses received from the pulse generator. A workpiece may be driven smoothly and continuously over a predetermined distance by the steady flow of fluid from the pulse smoother merely by providing the necessary number of electrical signals to the pulse generator.

Abstract: A fluid pulse smoother is described which receives pulses of fluid to provide a continuous drive for a workpiece. The pulse smoother receives a sequence of periodic fluid pulses, as from a pulse generator, and integrates or spreads each received fluid pulse over the time duration of each pulse. Consequently, a workpiece may receive a driving fluid flow which is continuous but whose rate of flow is substantially equivalent to the rate of fluid flow associated with the fluid pulses. Hence, the pulse smoother provides a fluid control system for converting a sequence of fluid pulses to a continuous fluid flow of a known volume and flow rate for precisely driving a fluid controlled workpiece.
