Abstract
The invention relates to a spray head having a slot-shaped central air outlet opening and preferably a slot-shaped paint nozzle for forming a flat jet of paint in an air-propelled application process.
Claims20
A spray head for producing a paint fan jet from at least one of a paint spray gun and a paint spray lance, the spray head comprising:
- an air gate;
- a paint nozzle having a needle valve;
- an air cap arranged downstream of the air gate in a direction of air flow;
- a passage opening for the paint nozzle to pass, arranged centrally in the air gate;
- a passage opening arranged centrally in the air cap for at least one of the paint jet and the paint nozzle and a jacket air flow surrounding the at least one of the paint jet and the paint nozzle to pass;
- at least one air passage opening radially spaced apart from the centrally arranged passage opening in the air gate;
- at least one air deflecting means arranged on an air passage opening associated therewith in the air cap, and deflecting a passing air jet in a direction of at least one of the paint jet and the paint jet and the jacket air flow surrounding the paint jet;
- wherein the air passage opening in the air cap and the at least one air passage opening in the air gate have a comparable radial distance from the center of the air cap and the air gate, respectively,
- wherein the central passage opening in the air cap is made as a slotted air cap opening with a longitudinal length of the air cap opening and a transverse length of the air cap opening, made to be shorter than said longitudinal length,
- wherein the paint nozzle is made as a slotted paint nozzle opening with a longitudinal length of the paint nozzle opening and a transverse length of the paint nozzle opening, made to be shorter than said longitudinal length,
- wherein said longitudinal length and said transverse length of the paint nozzle opening extend parallel to said longitudinal length and said transverse length, respectively, of the central air cap opening in the air cap, and
- wherein the air deflecting means is arranged on a small face of the central air cap opening along said longitudinal length, and a paint jet leaving the spray head is broadened along said transverse length of the air cap opening.
