Patent ID: 8820424

Claim:
A fire fighting nozzle comprising: a nozzle body with a proximal inlet, a distal outlet, and a passageway extending from the inlet to the outlet, the outlet defining an annular water flow pattern defining a void area therewithin; a stem located in the passageway about which fluid flows when fluid is flowing through the passageway; and a projecting body comprising a base mounted to said fire fighting nozzle proximate said distal outlet and a distal end downstream of said base, such that said projecting body projects distally outwardly from the nozzle body away from the stem, the projecting body contained within the void area and at least partially filling the space beyond the nozzle outlet where water exits the nozzle assembly such that a vacuum created within the space beyond the nozzle outlet when a water stream exits the nozzle has a reduced effect on the water stream, the projecting body comprising a tapered outer surface in which a cross-sectional area of said projecting body does not increase from said base of said projecting body to said distal end of said projecting body, whereby said cross-sectional area is greater at said base than at said distal end.
