ABSTRACT:
An ultrasonic nozzle includes an atomizing surface for producing an atomized liquid spray; a liquid-feed passageway for supplying the process liquid to the atomizing surface, the passageway having a first diameter section and a second fluidly connected smaller diameter section, with a shoulder defined therebetween; an internal shut-off assembly for preventing the supply of process liquid to the atomizing surface, the shut-off assembly including a shut-off rod slidably positioned within the passageway and having a sealing end adapted to cooperate with the shoulder to prevent the supply of process liquid to the atomizing surface, an actuator piston connected with the opposite end of the shut-off rod and slidable within a cylinder bore that is in fluid communication with the passageway, and a valve actuator for slidably moving the piston and shut-off rod in the passageway between a first closed position in which the supply of liquid to the atomizing surface is prevented and a second open position in which the supply of liquid to the atomizing surface is permitted; a barrier fluid provided in the cylinder bore between the passageway and the piston at a pressure higher than that of the process fluid in the passageway to prevent the process fluid from adversely affecting the shut-off assembly; and a substantially frusto-conical air guide in concentric surrounding relation to the atomizing surface at the tip of the nozzle to direct and diffuse the spray formed at the atomizing surface.
