Abstract
Viscous fluids are dispensed intermittently in regulated quantities from a body of such a fluid held under maintained pressure and under the control of a control valve in a fluid flow path positioned at a significant distance upstream of a discharge point, the flow path between the control valve and the discharge point having its contained volume adjusted in coordination with operation of the control valve so that as the valve closes the volume is increased to prevent exudation of fluid at the discharge point.
