ABSTRACT:
A manual spray dispenser for pressurizing a liquid to a predetermined pressure is provided. The spray dispenser includes a pressure adjustment assembly to adjust the predetermined pressure between a preselected range of pressures. The pressure adjustment assembly includes an adjustable biasing member to supply a force to a pressure chamber check valve in a direction opposite the flow of liquid from the reservoir to the atmosphere so that the pressure in the delivery passageway can be varied. Optionally, a two-hole rotating nozzle is provided in combination with a pressure adjustment assembly. In another aspect of the invention, an exit orifice purge system is provided to reduce dripping from the nozzle in the manual sprayer after dispensing.
