Abstract
A washing attachment for a compressed fluid spray gun is disclosed. The washing attachment includes a conduit, having a compressed fluid passageway positioned on the discharge end of the spray gun. An elongated member defining first, second and third passageways is in communication with the conduit with the second passageway in communication with the compressed fluid passageway. The first passageway is in communication with a source of cleaning fluid, a valve regulates the flow of cleaning fluid to the first passageway. The second passageway also communicates with the first passageway establishing a region of reduced pressure for drawing cleaning fluid into the first passageway. The first, second and third passageway terminate in discharge apertures adjacent the elongated member discharge opening. An opening in the elongated member communicates with the third passageway and is connected to a source of water.
