Nozzles provide sprays of various intensity and pattern as well as directing the liquid from the syringe. At one end of the scale ‘Jet’ nozzles produce a single stream of liquid and at the other ‘Spray’ nozzles provide a fine mist. Spray nozzles do not come into use until the early 1900’s and before this the finer sprays were obtained from rose nozzles with very fine perforations Filling the syringe through the small perforations of the rose could be difficult so a quick (or fast) fill valve was sometimes provided. With spray nozzles a quick fill valves had to be provided, because the tiny aperture needed to produce the spray could not be used for filling the syringe. Quick fill valves for spray nozzles can be incorporated with the spray nozzle into a ‘Spray Head’, or they can be integrated into the spray nozzle. Spray heads can have interchangeable caps with different size apertures. The following provides an index to various nozzle types. Click on the text or picture for further details and more examples.
