Wet/dry hose end sprayer

A sprayer head configured to be removably mounted onto a concentrate tank of a hose end sprayer, the sprayer head comprising:

• a) a valve assembly including:
• i) a valve housing having a first end including an inlet opening and a second end including a flow opening and a concentrate opening configured to communicate with an open interior of the concentrate tank;
• and
• ii) a valve body within the valve housing between the inlet opening and the flow opening, wherein said valve body further includes first and second flow orifices selectively positionable to communicate with said flow opening, a concentrate orifice selectively positionable to communicate with said concentrate opening, and a vent opening selectively positionable to communicate with said concentrate opening, the valve body being selectively movable between a closed orientation, a wet mode orientation, and a dry mode orientation, wherein said valve body has a first axis of rotation;
• b) a flow tube having a first end coupled to the flow opening of the valve housing, wherein the flow tube includes a venturi constriction and an injection orifice at or downstream of the venturi constriction;
• and
• c) a metering plate defining a first annular series of recesses comprising spaced-apart flow-metering holes, wherein successive respective flow-metering holes have an increasing hole diameter adapted to withdraw a selectively adjustable amount of a concentrate from the concentrate tank when said valve body is in either said wet mode orientation or said dry mode orientation, wherein said metering plate has a second axis of rotation which intersects with said first axis of rotation and forms an acute angle therebetween.
