  • Publication number: 20030173419
    Abstract: A spray gun pressure stabilizer of the present invention comprises a nozzle, a spray head and a spray gun, the spray head is threaded to the front end of the spray gun and is composed of a spray hole and air outlets at the center portion axially, the front end of the spray gun is further composed of a recess for a de-pressure ring to sleeve thereon, the recess comprises an air outlet and a de-pressure hole, the recess also has a threaded inner hole to connect with the nozzle. The improvements of this invention is to form a pipe at center portion of the nozzle, and extending therefrom a block rim, the nozzle further comprises a circular rim with a number of air holes, so that air flows through the air holes will be blocked by the block rim, which de-presses the air to provide a stabilization of air output.

  • Patent number: 6612506
    Abstract: A spray gun head includes, a diverter bushing, a nozzle body, an air cap and a locking ring. First and second vent holes are separately provided in the spray gun head. The diverter bushing is provided with a plurality of jets disposed in relation to the first vent hole to form a first air port. The nozzle body is provided with an airflow guide ring having airflow guide holes disposed relative to the inner wall of the diverter bushing to form a second air port. A plurality of first jets and second jets are provided in the air cap which guards the nozzle body. Air from the first and the second vent holes flows-through the first air port, the second air port air, the diverter bushing and the airflow holes in the airflow guide ring to be respectively ejected from both air jets.

  • Patent number: 6547161
    Abstract: This invention relates to an improved pressure regulation structure at the tip of the spray gun connected to the nozzle. A screw hole is formed in the front section of a passage where a regulation shaft extends from the tip of the spray gun. An inner recess and an outer recess are formed on the front surface of the spray gun respectively with an air outlet. A gasket with slots is inserted between the spray gun and the nozzle. A hollow screwed tube formed in the rear of the nozzle to receive insertion of the gasket before being engaged to the screw hole of the spray gun. An inner recess and an outer recess with air ventilating holes and air outlets formed in the nozzle. A groove is formed around a nozzle tip at the front side of the nozzle. The inner and outer recesses of the nozzle abutted to the inner and outer recesses of the spray gun to form a pressure regulation air port; and outer threads provided on the nozzle to receive a nut for the spray head connected to a nut to hold against the nozzle.
