Abstract
Abstract Beverage dispensing apparatus having an adjustable stroke, positive displacement pump unit, coupled to a reservoir which holds an inverted beverage bottle. The pump unit is adaptable to installation in an assembly of several units in rack form, with a single drive motor, each unit being selectively operable. Single or multiple units can be connected to a variety of actuating means and delivery spout or nozzle arrangements, each unit being readily removable for servicing. When actuated, the pump drive mechanism completes a single cycle to drive the selected pump through a preset dispensing and recharging stroke, and is capable of delivering the liquid for a considerable distance to an outlet.
