Abstract
A nozzle is pressure activated to generate a fine droplet, conical spray. The nozzle has an outer tubular body with a fluid inlet opening at one end and a discharge opening at its opposite end. Coaxially disposed within the body is a conduit for carrying fluid from the inlet to the discharge opening. Adjacent the inlet end of the nozzle, the conduit includes an annular flange with fluid seal between the peripheral edge of the flange and the inner wall of the nozzle body. The conduit is axially movable within the tubular body over a predetermined distance. Adjacent the discharge end of the nozzle is a helical opening through the wall of the conduit. The helical opening is spaced for the discharge end of the conduit less than the extent of axial movement of the conduit. A closure plate is disposed at the outer end of the conduit for shutting off flow of fluid through the nozzle. A coil spring is disposed about the conduit and has one end engaged with a wall portion of the nozzle body and its opposite end is engaged with the inner surface of the flange for releasably urging the conduit toward the inlet opening to maintain the closure plate in nozzle closing relation at the discharge end of the nozzle.
