Spray gun with liquid passages and outlet openings noncircular air horns.

摘要

A liquid spray gun comprising: a body assembly and platform portion including the body assembly a mouthpiece with an outlet end, said mouthpiece a passageway for liquid extending from one inlet end to an outlet end that opens through the outlet end of the nozzle portion, said body assembly a first duct air passage extending from an inlet end to an outlet end at the end output said nozzle portion, said outlet end of said first passage of air around said outlet end of said passageway outlet liquid at a pressure greater extending and being shaped to direct air, atmospheric against liquid exiting the outlet end of the passageway to propel liquid outlet fluid away from the outlet end of the mouthpiece Mient flush liquid is formed into a generally conical stream about an axis, said body assembly elongate limbs or horns projecting past the outlet end of the nozzle on opposite sides of said axis, said joint body a second duct air passage extending from an inlet end through portions of said horns to conduits outlet passage having openings spaced outlet along said horns from the outlet end nozzle and facing opposite sides of said axis, being noncircular said passageways and said openings, outlet, and being shaped to direct air at greater than atmospheric pressure, flowing through said second conduit air passage against opposite sides of a generally conical liquid stream is formed by air flowing through the first passage d and air to restore to the generally conical stream of liquid in the form of a wide and elongated current, characterized in that said body assembly including a polymeric piece molded air cap portion having said horns and means mounting said polymer molded part air cap on said nozzle portion, said molded part air cap and surface nozzle forming said first and second passageways air, said passageways and said openings output noncircular being formed by said molding, wherein said body assembly is molded from polymer material and said platform portion is made of metal.
