ABSTRACT:
A pump sprayer is disclosed for dispensing fluids such as insecticides and herbicides. The sprayer comprises a supply container which holds the fluid to be dispensed, a manually-operated piston pump, a pressure vessel or accumulator, and a manual control valve for controlling fluid dispensed through a spray wand. The accumulator includes an elastomeric bladder which is adapted to accumulate fluid from the pump and to deliver the fluid to the spray wand at a desired pressure. In order to provide a pump sprayer which can deliver fluid at a substantially constant pressure from a fluid supply contained in conventional containers, the pump and elastomeric bladder are configured to pass through the fill openings of the containers and to be secured therein during operation of the sprayer.
