Abstract
A fire-hose nozzle includes a cylindrical housing having an inlet, an outlet and a water passageway therebetween. Centrally disposed within the passageway is an elongated, rocket-shaped stem having a larger-diameter end near the inlet and a pointed, tapered end near the outlet. Proximal the inlet are circumferentially disposed apertures for injecting ambient air into incoming water to widen the spray pattern through the outlet. Attached to the inlet is a pistol-grip controller for coupling with a conventional fire hose. Therefore, when water is delivered to the housing, the stem disrupts and separates the water stream to decrease hose back pressure, recoil and oscillation.
Claims16
A fire-hose nozzle comprising:
- a housing having an inlet, an outlet and an interior water passageway therebetween;
- an elongated, rocket-shaped stem within said water passageway and fixedly attached to said housing with bolts radially extending from said stem to said housing that axially suspend said stem within said water passageway, said stem having a large-diameter tubular portion near the inlet and a tapered, pointed portion near the outlet;
- a controller coupled with said inlet and a fire hose distal end for controlling water flow from said hose to said water passageway, whereby when water is delivered to said passageway, the stem disrupts and separates incoming water to decrease back pressure, recoil and oscillation of said fire hose.
A fire-hose nozzle comprising:
- a housing having an inlet, an outlet and an interior water passageway therebetween;
- an elongated, rocket-shaped stem within said water passageway and fixedly attached to said housing with bolts radially extending from said stem to said housing that axially suspend said stem within said water passageway;
- a controller coupled with said inlet and a fire-hose distal end for controlling water flow from a fire hose to said water passageway, whereby when water is delivered to said passageway, the stem disrupts and separates incoming water to decrease back pressure, recoil and oscillation of said fire hose.
A fire-hose nozzle comprising:
- a housing having an inlet, an outlet and an interior water passageway therebetween;
- an elongated, rocket-shaped stem centrally suspended within said water passageway, said rocket-shaped stem fixedly attached to said housing;
- a controller coupled with said inlet and a fire hose distal end for controlling water flow from a fire hose to said water passageway, whereby when water is delivered to said passageway, the stem disrupts and separates incoming water to decrease back pressure, recoil and oscillation of said fire hose;
- a plurality of apertures circumferentially disposed around the inlet of said housing for injecting ambient air into incoming water to widen a spray pattern through said outlet, and to atomize incoming water to more effectively extinguish a fire;
- a collar slidably mounted on said housing for selectively covering and exposing said apertures;
- a biased latch on said housing, said biased latch having a pin that rides within a slot on said collar to prevent inadvertent removal thereof.
