ABSTRACT:
The sprayer comprises two main functioning units; namely, a flow control system incorporated in the chemical concentrate jar top closure and a spray nozzle integral with the closure for dispensing dilute solutions of fertilizer, pesticides and the like as supplied by the flow control system. The control system comprises an ejector for drawing concentrate from the reservoir jar and a pair of coaxial, independently rotatable valve elements, one, acting with fixed structure, serving to turn the water supply off or direct the water into the chemical concentrate jar or through the unit to the spray nozzle, the other, operating in conjunction with the first valve element, controlling by means of flow resistance in a labyrinth, desirably in conjunction with an orifice metering disc, proportionate feed from the jar of chemical concentrate to the main water stream. Proportionate feed may be accomplished without the flow resistance control by appropriate dimensioning of the ejector. The ejector is itself novel in that it is made of plastic material by injection with a single mold having a single core forming the entire length of the ejector passageway. The spray nozzle includes an adjustable, cam-controlled baffle for selectively achieving a downwardly or upwardly directed spread spray pattern or a jet stream.
