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.
