Abstract
Abstract A pressure spraying apparatus for spraying fluids comprising a fluid reservoir tank and a fluid handling assembly including a pump assembly attached in fluid communication therewith, fluid transfer assembly and fluid supply assembly each communicating with the fluid reservoir tank through the fluid handling assembly. The fluid transfer assembly and fluid supply assembly are coupled to one another through a plurality of selectively controlled valves and attached conduits comprise the fluid handling assembly to control the intake and dispensing of fluid into and from the pressure spraying apparatus through the pump assembly.
