Abstract: Various spray devices are presented for mixing two media. A device can include a housing, a first supply line for supplying a first medium, a second supply line for supplying a second medium, and a flow channel leading to a nozzle. The first and second media, for example, a gas and a liquid, respectively, can be mixed in various ways. Following such mixing, the mixed media are guided to an outlet nozzle or bore, and ejected. Using injection molding techniques, very fine grooves can be made in an exemplary spray nozzle device, by appropriately fashioning an injection mold. By carefully controlling the size, shape and dimensions of such grooves, and the pressures at which the two media are fed to the spray nozzle device, a correct ratio of air to liquid can be precisely maintained, which is key to obtaining a desired spray or foam as to droplet size, droplet speed, and type of spray, mist or foam.
