Patent ID: 8313044

Claim:
A method for operating a firefighting nozzle comprising a nozzle body with an inlet and an outlet, a fluid passageway defining a flow path extending between the inlet and the outlet, the outlet defining an outlet cross-sectional area, and an adjuster mounted onto the nozzle body, the adjuster adjustable from a first position to a second position by application of an adjustment force, such that the outlet cross-sectional area is limited by the adjuster to a smaller cross-sectional area in the second position as compared to the first position, the method comprising the steps of: directing a flow of pressurized fluid through the fluid passageway; and redirecting a portion of the pressurized fluid from the flow path of the fluid passageway, the redirected fluid applying a fluid force on the adjuster which urges the adjuster toward the second position, such that the adjustment force required to adjust the adjuster from the first position to the second position is reduced by application of the fluid force.
