ABSTRACT:
A hose-end sprayer has a selectively rotatable rotary valve received within the transverse bore of a housing which includes a carrier liquid inlet passage, a chemical liquid inlet passage and a discharge passage. The valve has a carrier liquid duct and a chemical liquid duct opening into the carrier duct for interconnecting the inlet passage in a first rotative position of the valve, and the valve is capable of closing the inlet passages in a second rotative position of the valve. The rotary valve is selectively rotatable in a third position for interconnecting the liquid passage only with the discharge passage in a rinse position of the valve. Container venting is isolated from a valve chamber in which the rotary valve operates to avoid entry of carrier liquid into the container through the open vent in the ON position of the valve upon its selective rotation.
