<p>A spraying device (10) includes a compound fourway rotatable control valve (30), and additive fluid control disc member (84) and a spray selector disc member (104), whereby a primary fluid, such as water, and an additive fluid, such as detergent, can be sprayed or dispensed in various spray patterns separately, or as a mixture having selectively variable concentrations of the additive fluid in the primary fluid. The compound fourway rotatable valve (30) is movable from an inoperative ''OFF'' position into first, second and third ''WATER RINSE'', ''SOAP-AND-WATER'' and ''SUDS ONLY'' operative position. The control disc member (84) includes a plurality of orifices (86) of various diameters for controlling the amount of additive fluid dispensed into the primary fluid from a resilient bladder (16) containing the additive fluid as the bladder is collapsed in response to external pressure thereon by the primary fluid. The spray selector disc member (104) provides various spray patterns as the result of having orifices (112) of various configurations formed therethrough and selectively positionable in alignment with a discharge orifice of the device. A telescoping spray tube assembly (122), which telescopes outwardly in response to fluid pressure, may be utilized in place of the spray selector disc member (104).</p> |
