Abstract
A sprayer head assembly for dispensing a chemical stored within a container comprises a body having a bore and a valve moveably positioned at least partially within the bore. The housing includes passages for carrier fluid and the chemical. A vent passage is also provided. The valve selectively closes and opens the carrier fluid, chemical and vent passages. The valve is configured to move in a side to side motion which is generally transverse to a longitudinal axis of the assembly.
