    Abstract: The present invention relates to a fluid injection system comprising a tubular member (12) arranged to form part of a fluid line through which, in use, fluid flows under pressure, a venturi (14) contained within the tubular member (12), first and second volumes arranged to contain first and second fluids respectively, said first and second volumes being separated by a pressure responsive means such as a bladder (30), the tubular member (12) on a high pressure side of the venturi (14) being in fluid communication with said first volume, and a metering line (40) extending from the tubular member on a low pressure side of the venturi and being in fluid communication with said second volume, the arrangement being such that, in use a pressure differential is created across the venturi (14) so that the first volume is increased by fluid passing from the fluid line (12) into the first volume and by movement of the pressure responsive means, the second volume is correspondingly decreased by fluid passing therefrom through the conduit into the fluid flowing through the fluid line, wherein bypass conduit means (50) is provided between the high pressure side of the venturi and the line (12) on the low pressure side of the venturi (14) so as to provide an alternate flow of fluid in the line and modify through volumetric displacement the rate of flow of the second fluid.

    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.

    Abstract: An injector for injecting into a flow of a first liquid passing through a flow passage formed in the body of the injector a second liquid, which is pressurized for injection by the pressure of the first liquid. Pressurization of the second liquid is accomplished by means of a liquid-tight canister separated into first and second pressure chambers by a flexible diaphragm. The pressure of the first liquid flowing through the injector is tapped off to pressurize the first pressure chamber, and through the diaphragm, the second chamber containing the second liquid. The second chamber is connected to the flow passage at a point downstream of the point where the pressure of the first liquid is tapped off to pressurize the canister, and the passage is venturi-shaped adjacent the point at which the second liquid is injected into the flow passage to provide an additional force drawing the second liquid into the flow passage. A second embodiment of canister, which is nearly double the capacity of the first is disclosed, as well as a system for refilling the canisters.

    Abstract: A trigger actuated fertilizer spray gun has a herbicide injector mounted on its muzzle with the valve for the injector having an actuator which is also accessible from the handle of the gun, so that an operator, while spraying fertilizer, can make spot applications of a herbicide as weeds are encountered in the area being fertilized. The herbicide is carried in a canister which can either be mounted on the handle of the spray gun or on a belt worn by the operator and the canister is divided into first and second, variable volume chambers by a flexible diaphragm. The first chamber is connected to the flow passage of the fertilizer to pressurize it to approximately the line pressure of the fertilizer flow, and the second chamber, containing the herbicide, is connected to the injector at a venturi-shaped portion of a passage through it. The second, herbicide filled chamber is therefore under pressure exerted by the diaphragm so that when the valve is opened the herbicide is sprayed into the flow of fertilizer passing through the injector. The venturi-shaped portion of the passage at the point where the herbicide is injected into the fertilizer flow also facilitates herbicide flow so that there is an almost instantaneous flow of herbicide into the fertilizer when the valve is actuated.

    Abstract: A dispensing device having a rotor projecting into and rotatable by a fluid stream for metering a material into such fluid stream. The rotor is exposed to the desired material in a reservoir and, upon rotation of the rotor by the fluid stream, serves to transfer the material from the reservoir to the fluid stream. A lock screw is provided for preventing such transfer when metering of the material is not desired.
