Abstract: A multiple dilution ratio hose-end sprayer having a rotatable selector dial having a plurality of orifices and associated cavities. The orifices are adapted to intersect a fluid passageway extending from a fluid container to a mixing chamber used for mixing selected amounts of fluid from the container with water entering the mixing chamber. Water is supplied to the mixing chamber through a first and second spaced apart nozzles, an annular channel extending from between said nozzles to an intersecting channel adapted to communicate with a cavity associated with an orifice intersecting said fluid passageway. The nozzle opening from said second nozzle being smaller than the discharge opening for the sprayer, but preferably equal to or smaller than opening from the first nozzle.

Abstract: An impulse sprinkler assembly is provided with a liquid stream-intersecting arm formable by open-and-shut injection molding techniques and having a pair of stream-diverting surfaces. Control over the direction of stream discharge is improved by providing a plurality of upraised ribs on the face of at least one of the stream diverting surfaces to minimize liquid thickness nonuniformities during flow thereacross.
