ABSTRACT:
A portable pump spraying device includes a container for the liquid to be sprayed, a housing positioned above the container having a spraying chamber, a pumping unit to elevate the liquid to the spraying chamber, and a rotating disc in the spraying chamber to attenuate and impel the liquid by centrifugal force through an egress port in the housing. Interceptor baffles within the spraying chamber finely trim the liquid spray as it leaves the egress port and direct the excess liquid back to a reservoir for recirculation. The pumping unit includes a rod that is reciprocated by an eccentric on the rotating shaft on which the disc is mounted. The rod acts as a piston which on its suction stroke withdraws liquid from the container and on its compression stroke discharges the withdrawn liquid and forces it through a nozzle onto the disc in the spraying chamber. In one form of the invention, the volume of liquid being pumped by the pumping unit may be varied for varying the amount of liquid being sprayed without varying the speed of the pump drive motor and thus the speed of the disc driven thereby.
