Abstract
The comestible fluid dispensing system of the present invention preferably employs a pump or valve operable to control movement of comestible fluid from a comestible fluid source to a tap provided with a draw-back valve. The draw-back valve is preferably capable of drawing comestible fluid in an upstream direction in the tap during closure of the draw-back valve. Preferably, suction generated by closure of the draw-back valve is employed for one or more purposes including: to remove comestible fluid dangling from the tap, to draw comestible fluid into the tap away from view and from exposure to the environment, to reduce comestible fluid buildup on and near the tap outlet, to enclose or at least partially enclose comestible fluid downstream of the draw-back valve, and to operate a downstream cutoff valve in the tap. A damper is employed in some embodiments to control valve movement.
