Abstract
In an airless dispensing system, liquids may be dispensed at variable angles from substantially 0° to as much as 50°-60°, by a simple adjustment made by a dispenser operator without ceasing operation or disassembling the dispenser apparatus. A variable angle liquid dispenser comprises a nozzle having a forward face with a dispensing orifice, a first passageway in the nozzle having a central axis intersecting the dispensing orifice, a plurality of angled second passageways in the nozzle, each angled second passageway having a central axis intersecting the dispensing orifice and the central axis of the first passageway, and a variable flow control adjustable to vary the flows of liquid entering the first passageway and the plurality of angled second passageways and to thereby vary the included angle of the liquid dispensed from the dispensing orifice and the width of liquid that may be applied to a substrate.
