Abstract:
A high pressure misting nozzle comprising:a) a nozzle stem body having a fluid inlet and a first chamber in communication with the fluid inlet; b) a fogger nozzle attached to the nozzle stem body, the fogger nozzle having a nozzle orifice and a second chamber in communication with the nozzle orifice and the first chamber; c) a valve member movably located in the first chamber and movable between a closed position preventing fluid communication between the fluid inlet and the first chamber, and an open position allowing fluid communication between the fluid inlet and the first chamber whereby fluid may enter the first and second chambers; d) a nozzle pin having a longitudinal axis removably located in the second chamber, the nozzle pin having a fluid metering portion and being movable along the longitudinal axis between a first position in which the nozzle pin is displaced away from the nozzle orifice, and a second position in which the nozzle pin is located adjacent to the nozzle orifice, whereby fluid entering the second chamber urges the nozzle pin toward the second position, the nozzle pin being generally cylindrical in configuration having first and second ends, and wherein the fluid metering portion comprises at least one fluid metering notch located in the first end; and, e) a helical coil spring acting on the valve member, the helical coil spring having a first end with a cross member extending at least partially along a diameter of the helical coil spring, whereby the nozzle pin rests on the cross member when in the first position.
