    Abstract: A blowing device for compressed air or the like comprising at least one supply channel (15) which is connectable to a source of compressed air and the outlet(s) (19) of which is, (are) shaped to impart to the compressed air a jet in the form of a ring or part of a ring, and further comprising at least one communication channel (20) adapted to connect the inside of the jet (C) with the atmosphere. The object of the invention is to provide a blow nozzle with a large contact surface between outflowing pressurized air and the ambient air in order to provide an airflow with a low sound level, a large momentum, high efficiency and reduce striking velocity against the object intended to be cooled, dried or blown clean. This has been attained in that the product of, on the one hand, the ratio between the outer plus the inner circumference (O2 and O1) of the outlet (19) and its area (Aout) and, on the other hand the inner diameter (D) of the outlet and its width (S), is at least 4 mm/mm , preferably considerably larger than 4 mm/mm .

    Abstract: The nozzle comprises an internal chamber (8) supplied with pressurized fluid which communicates with an annular discharge orifice (5). It comprises an internal channel (2) centered on the annular orifice axis and whose diameter corresponds substantially to the diameter of said annular orifice, said channel providing for a double flow around the nozzle and the fluid film coming out of the orifice. The nozzle may be used to spray all types of fluids: water, fuel, in applications involving high flow rates in the order of 5 to 60m3/h, yet in very fine droplets. The spraying device fitted with such nozzle comprises preferably two contrarotary fans (22 and 23). The nozzle (1) may also be provided with nucleators (70) arranged on its periphery so as to provide seeding of the water/air mixture for the production of artificial snow. The disclosed spraying device has the advantage of being particularly compact.

    Abstract: A method of atomization control and related gas atomizing nozzles are described which enable variation of the degree of atomization, the liquid and gas flow rates and the atmospheric spray dilution. Varying the thickness of flowing liquid and adjacent atomizing gas sheets varies spray droplet size and atmospheric spray dilution. Transverse sheet size is varied to change nozzle capacity. Annular and linear sheet forming nozzles are described. Nozzles are also described with flexible divider walls whereby thickness of the flowing sheets may be varied by altering relative flow pressures.

    Abstract: A liquid discharge nozzle having no moving parts, includes a hollow body defining a liquid inlet at one end and an outlet opening at the other end. The body has an internal chamber arranged in communication with both the inlet and outlet ends of the body. A plug, having substantial length between opposite end surfaces, is disposed across the chamber inwardly of the bodyoutlet end and grooves in the sidewalls of the plug define constricted liquid-outlet means from the body. An air duct extends through the plug from adjacent the body outlet to the exterior of the body between the plug and inlet end of the body.
