Abstract
Abstract A liquid diffusion-spraying mechanism having an air motor for driving a rotary cage or slinger which carries impeller blades outwardly of the cage. A nozzle, passing through the central portion of the air motor, discharges liquid against a central baffle which deflects the liquid outwardly. Thence, the liquid passes through a peripheral screen in the cage and is broken up in small particles which are slung into the path of air created by the impeller blades. A group of the liquid diffusion-spraying mechanisms are readily arranged on a spray boom in spaced relationship, the axes of the mechanisms being parallel to each other. The air motors are arranged in series so that compressed air from a single source passes successively through the air motors for driving each of them. Valves are provided by which one or several of the mechanisms may be shut off.
