ABSTRACT:
This invention relates to a device for forming a mist or fog having a convex surface which receives and expands a fluid delivered thereto. The convex surface of the device has a number of circular protrusions spaced peripherally thereon, separated by a number of slots having holes therein. The holes communicate with an inner cylindrical chamber. Suction is produced through the holes when the fluid stream passes over them, to automatically add a further fluid to the fluid being expanded by the device. A cylindrical sleeve surrounds and protects the device. The device is supported in the cylindrical sleeve, either in front of a nozzle by an annular structure, or by a bent tube held in the cylindrical sleeve in front of the device, or in a venturi. When fluid from the nozzle or entering the cylindrical sleeve is expanded by the convex surface, it pulls a further fluid through the slots to mix with the injected fluid separated from the convex surface of the device at greater speed, thus forming a mixed fog of fluid.
