发明名称 Longitudinal valve ready to use hose end sprayer
摘要 A sprayer head assembly comprises a sprayer head and a valve for controlling the flow of fluid through the assembly. The sprayer head comprises a chemical passage, a carrier fluid passage and a vent passage. A generally cylindrical bore is in communication with the chemical, vent carrier fluid passages. The valve is moveably positioned within the bore. The valve is moveable between a first position and a second position. The valve comprises a first passage and a chemical inlet passage that is in communication with the first passage. In the first position, the valve blocks the vent, chemical and carrier fluid passages. In the second position, the first passage is configured to be in communication with the carrier fluid passage while the chemical fluid passage is in communication with the chemical inlet passage. The valve defines a suction generating recess positioned within the first passage. The chemical inlet passage communicates with the first passage through an opening positioned within the suction generating recess. The first passage defines an outlet for discharging the carrier fluid and chemical in a first direction and the valve is rotatable about an axis that extends generally parallel to the first direction.
