<p>A multiple dilution ratio hose-end sprayer (10) having a rotatable selector dial (19) having a plurality of orifices (84) and associated cavities (85). The orifices (84) are adapted to intersect a fluid passageway (71) extending from a fluid container (18) to a mixing chamber (62) used for mixing selected amounts of fluid from the container (18) with water entering the mixing chamber (62). Water is supplied to the mixing chamber (62) through a first and second spaced apart nozzles (68, 75), an annular channel (70) extending from between said nozzles to an intersecting channel (72) adapted to communicate with a cavity (85) associated with an orifice (84) intersecting said fluid passageay (71). The nozzle opening (75a) from said second nozzle (75) being smaller than the discharge opening (66a) for the sprayer, but preferably equal to or smaller than the opening (69) from the first nozzle (68). </p> |
