Abstract
A nozzle for dispensing a fluid having a barrel having a proximal end and a distal end, the barrel having a passage defined by a first internal surface extending between the distal end and the proximal end, and an orifice defined by a second internal surface at the distal end of the barrel, a stem located at least partially in the barrel, the barrel is movable in relation to the stem to switch between a low pressure mode and a high pressure mode, a shaper located around an outer surface of the distal end of the barrel, the shaper being movable in relation to the barrel to switch between a low pressure fog mode and a low pressure stream mode. The nozzle is configured to dispense the fluid in a straight stream or fog in both the low pressure mode and the ultra-high pressure mode. The orifice is also configured to provide flushing capability for the ultra-high pressure mode while operating in the low pressure mode.
