Abstract

An adjustable flow rate nozzle for atomizing liquids comprises a tubular-like body for conducting a liquid under pressure having a discharge end terminating in a single plane surface, a structured device having a single plane surface which is attached with its plane surface contiguous with the plane surface of the tubular-like conduit and a slit-like aperature formed between the single plane surfaces of the tubular-like conduit and the structured device. The size of the slit-like aperture and thus the atomized flow rate is adjustable by securing structured devices to cooperate with the discharge end of the tubular-like body. The tubular body contains a main feed cavity of relatively large circular cross section and at least one corona cavity which is elongated outwardly from the main feed cavity. The corona cavity includes a pair of spaced sidewalls extending outwardly from the main feed cavity and an arcuate end wall joining the spaced side walls remote from the main feed cavity. The main feed cavity is internally threaded to receive a screw by which the structured device is positioned and fastened to the discharge end of the tubular-like body. In some embodiments of the invention, the structured device is formed separate from the screw used to hold it to the tubular body, while in other embodiments the head of the screw is modified to form the structured device.
