Each cavity may be proportioned together with the orifice to provide the desired dilution ratio. Mixing head 11 includes nozzle portion 16 having spray deflector 17. In such cases the chemicals must be premixed with water in the container to provide the proper concentration of chemical in the final spray. Accordingly, it is an object of the present invention to provide a multiple ratio hose-end sprayer having a multiple fluid orifice selector dial which is easy to remove for cleaning, but precisely alignable in operation to provide accurate dilution ratios. First retainer spring 82 biases retainer means 91 against dial 19 and the bottom of nozzle end 16. Unique Spray Deflector Attachment. Bifen it hose end sprayer setting. Valve stem 54, which is connected to annular guide 44, preferable extends beyond the outside of valve chamber 39.

Preferably, inner surface 96 of holding means 93 is tapered to accommodate tube 97 which compressively fits within and extends into container 18. 9. 2. THANKS, ALEX. Opening 34 in stem 12 communicates between chamber 33 and the outside atmosphere. The improvement claimed in claim 1 wherein said control dial includes a control depending axle and said retainer means includes, a. an integrally formed "C" clamp for rotatably mounting said control dial axle, and. While the present invention will work satisfactorily with water pressures between 20 and 80 psi, it is more preferable to maintain the pressure at between 40 to 60 psi. The improvement claimed in claim 1 wherein the size of each cavity is proportioned to provide a selected dilution ratio. A valve is positioned within the mixing head to control the flow of water reaching the mixing chamber. Housing 26 is retained within hose connector end 13 by means of hose washer 27. Because of the difference in diameter in the first and second bores, a partial vacuum is created in the fluid passageway causing the fluid in the container to be siphoned into the mixing chamber for dilution with the water. Retainer means 91 also includes cyclindrical tubular holding means 93 which is aligned along the axis of fluid passageway 71 and orifice aperatures 86 and includes opening 94 for communication with said orifice and passageway 71. Reply. A number of commercially available sprayers do provide for multiple dilution ratios. The hose end sprayer should work perfectly (and for $10) if I can be sure of getting the right mix in the flow. Concentrically mounted to annular guide 44 is closure sealing means 46 and "O" ring 47 mounted in front of guide 44. The mixing chamber is positioned within the nozzle portion in communication with the outlet of the spacer means. A fluid tight seal is maintained between fluid passageway 71, orifices 84 and opening 94 by means of a FIG. Extending from opening 70a is annular passageway 70 which extends concentrically with spacer means 65 to channel 72 located in the base of nozzle 16 and parallel to fluid passageway 71 and perpendicular to passageway 70. Privacy Policy The integrated passageway is aligned for communication with the orifices of the selector dial and the fluid passageway of the mixing head. Most hose-end sprayers have only one dilution ratio. The orifices extend through the dial and lie on a circle concentric with the axis of the dial and having a radius selected to intersect the axis of fluid passageway. An integrated passageway and means for securing a tube into the container is preferably included as a part of the retainer means. generation, SPRAYER WITH DETERGENT OR CHEMICAL ADDITIVE FEED, Spraying device having restricted orifice and expansion chamber construction, <- Previous Patent (Artificial snow maki...). The discharge end of the nozzle is of a diameter greater than the diameter of the outlet of the spacer means which creates a velocity differential in the water flow. & Terms of Use. Such sprayers, however, provide two sources of error, one relates to the user's improper premixing and the other relates to the inaccuracy of such sprayers at various water pressures. Basically, such units are relatively simple and inexpensive, using the domestic water pressure from a garden hose to power the spray. Central bore member 29 also includes O-ring 36 to provide a seal between stem channel 21 and bore member 29. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) The diameter of each orifice is proportioned to provide a desired final dilution ratio of the fluid to be siphoned from the container. 3) adapted to ride within detents 87 during rotation of dial 19. As can be seen from FIG. Anti-siphon means 22 consist of a retainer disc 23 having a plurality of water openings 24 on a circle concentrically spaced from the axis of disc 23. The water pressure forces open diaphragm 28 and presses it against shoulder 37 of housing 26 to sealingly close annular channels 32. Also manufacture supply wide range of garden tools watering irrigation products. Generally, the present invention comprises a mixing head having a mixing chamber for dilution of a chemical fluid with water. In a multiple dilution ratio hose-end sprayer having a mixing head containing a mixing chamber which includes a sprayer discharge outlet, a means for connecting a water source to said mixing head for supplying water to said mixing chamber, a means for securing a fluid container to said mixing head, passage means for conveying fluid from said container to said chamber and control means for varying the flow of fluid from said container to said chamber, the improvement therein comprising: a. said mixing chamber being in fluid communication with a fluid inlet means smaller than the sprayer discharge outlet; b. a rotable control dial having a plurality of orifices and associated cavities, said dial being rotably mounted adjacent said mixing head, said orifices and cavities being positioned on circles concentric with the axis of the dial which intersects the axis of fluid passage means for fluid communication between a selected orifice and said passage means, said cavities being positioned on the surface of the dial adjacent to the mixing head and in communication with said associated orifice; c. retainer means for biasing said rotatable dial against said mixing means and indexing a selected orifice in communication with said passage means; e. an intersecting channel extending from ahead of said mixing chamber to communicate with the cavity of the associated orifice indexed in communication with said passage means. Valve chamber 39 is in direct communication with water channel 21 of stem 12. In general, the mixing head is connected to the chemicals in the container by means of a siphon tube which extends from a mixing chamber into the bottom of the container. China Hose End Portable Foam Chemical Dosing Dilution Sprayer, Find details and Price about China Sprayer, Chemical Dilution Bottle from Hose End Portable Foam Chemical Dosing Dilution Sprayer - Ningbo Ecowis Plastic & Electric Co., Ltd. 4b is a bottom plan view of the selector dial; FIG.
