Abstract:

A stackable fluid dispensing apparatus has a case and a fluid manifold located within the case which is adapted to be connected to a source of pressurized fluid. A plurality of valves located within the case are connected to the fluid manifold by a plurality of fluid lines. A nozzle block on the case has a plurality of fluid dispensing openings positioned within an exterior face of the nozzle block in at least one line. Fluid tubes communicate each of the valves with a selected one of the nozzle block openings whereby actuation of the valves controls the flow of the fluid through the nozzle block openings. The dispensing openings at the outermost extents of the line in the nozzle block are located adjacent opposite edges of the exterior face. The distance from the center of each of the opposite outermost dispensing openings to the respective adjacent edge of the exterior face is one half the center to center distance of any two remaining dispensing openings in the line. The precise nozzle spacing on the nozzle block allows two or more of the devices to be stacked one upon the other without affecting overall print quality the nozzle block is removably mounted on the case to allow alternate nozzle blocks to be mounted on the case, the alternate nozzle blocks having different dispensing opening spacing.
