Abstract
An HVLP spray gun air cap having an axial passage with a cap opening on an outer side thereof, first and second air horns protruding from the outer side of the air cap on opposite sides of the cap opening, first and second diverging air passages disposed in the air cap having corresponding orifices on the outer side thereof, the first and second diverging air passages disposed on opposite sides of the cap opening and aligned perpendicular to air passages of the first and second air horns.
Claims20
A spray gun air cap, comprising:
- an axial passage having a cap opening on an outer side of the air cap;
- first and second air horns protruding from the outer side of the air cap on opposite sides of the cap opening;
- first and second diverging air passages disposed in the air cap having corresponding orifices on the outer side thereof,
- remaining portions of the outer side of the body member between the orifices of the first and second diverging air passages and the first and second air horns devoid of other air openings,
- the first and second diverging air passages disposed on opposite sides of the cap opening and aligned generally perpendicular to the first and second air horns.
An air cap for an HVLP spray gun nozzle assembly, comprising:
- a body member having an axial passage disposed therein, the axial passage having a cap opening on an outer side of the body member;
- a first air horn protruding from the outer side of the body member on one side of the cap opening, and a second air horn protruding from the outer side of the body member on an opposite side of the cap opening,
- the first and second air horns having corresponding horn air passages;
- first and second air passages extending through the body member having corresponding orifices on the outer side thereof, the outer side of the body member otherwise devoid of air openings, the first and second air passages diverging from the passage axis in a direction away from the outer side of the body member,
- the first and second air passages disposed on opposite sides of the cap opening and aligned perpendicular to the horn air passages.
In an HVLP spray gun air cap having an axial passage with a cap opening on an outer side thereof otherwise devoid of air openings, and first and second air horns protruding therefrom on diametrically opposing sides of the cap opening, the improved air cap comprising:
- a first air passage disposed in the air cap having a first orifice on the outer side thereof, the first air passage diverging from the passage axis in a direction away from the outer side of the air cap;
- a second air passage disposed in the air cap having a second orifice on the outer side thereof, the second air passage diverging from the passage axis in a direction away from the outer side of the air cap;
- the first and second air passages disposed on opposite sides of the cap opening and aligned generally perpendicular to the alignment of the first and second air horns.
