Abstract: A sprayer head may be removably mounted onto a concentrate tank of a hose end sprayer. The sprayer head may include a valve assembly having a valve body having a first axis of rotation selectively movable between a closed orientation, a wet mode orientation, and a dry mode orientation. A metering plate may include a first annular series of spaced-apart flow-metering holes with each successive respective flow-metering hole has an increasing hole diameter adapted to withdraw a selectively adjustable amount of a concentrate from the concentrate tank when the valve body is in either the wet mode orientation or the dry mode orientation. The metering plate has a second axis of rotation which is non-coaxial with the first axis of rotation.

Abstract: A hose end sprayer includes a concentrate tank and a sprayer head. The sprayer head has an inlet end, an outlet end and a flow tube, along with a suction tube and a valve. When the sprayer head is closed, neither the first nor the second flow orifice communicates with the flow opening and the concentrate opening is closed by the valve body. When the sprayer head is in wet mode, the vent opening communicates with the concentrate opening as concentrate is drawn into the flow tube. When the sprayer head is in dry mode, the concentrate orifice communicates with the concentrate opening to direct a portion of the fluid into the concentrate tank. A metering plate injects a selectively adjustable amount of concentrate into the fluid stream. The sprayer head may further include a concentrate basket to hold a dry product within the concentrate tank.
