Abstract
A hose-end sprayer includes a linearly actuated valve such as a poppet valve that is opened by means of pressure applied thereto from a pivoted lever. The lever and valve provide instant on and off action and one-handed control over the water flow. Pressurized water containing a mixed chemical is supplied to a spray defining nozzle in a closed system that maintains the water under full pressure until after it emerges from the nozzle. By preventing contact between the water and air until the spray pattern is formed, better definition of the pattern is obtained and nozzle drip is eliminated.
