Abstract
An embodiment of a nozzle comprising a nozzle adapter, a nozzle tip, and a plunger is provided. The nozzle adapter comprises an inner and outer surface, the inner surface having a helical groove, and a top end rotatably coupled to the nozzle adapter inner surface. The plunger comprises an outer surface, a top end, and a lower end that mates with the nozzle tip inner surface. At least one projection is along the body outer surface between the top end and the lower end keyed to fit within the helical groove of the nozzle tip, wherein the plunger and the nozzle tip are configured so that rotational motion of the nozzle tip causes axial motion of the plunger relative to the nozzle adapter without appreciable axial motion of the nozzle tip relative to the nozzle adapter.
