Atomiser head for spray guns for pneumatically spraying liquids

摘要

The invention relates to an atomiser head for spray guns for pneumatically spraying liquids in the form of an attachment component for conventional spray guns, which component brings about a substantial reduction in noise emission. The nozzle openings (4) for the liquid are shaped in such a way that a flat jet of liquid is formed. The nozzle openings (15) for the compressed air are arranged on the two sides of the nozzle openings (14) at a small distance such that the compressed air atomises the liquid in the jet of liquid which is flowing out and spreads it out in a fan-like manner. Further nozzles (16) for the compressed air assist the intake of the liquid. The nozzle openings (15) extend at the angle () of 0 DEG or greater than 0 DEG with respect to the direction of the axis of the spray jet and extend away from the direction of the axis of the spray jet at an angle (b) of 0 DEG or greater than 0 DEG . The nozzle openings (16) extend at the angle () of 0 DEG or greater than 0 DEG away from the direction of the axis of the spray jet. The nozzle opening (14) can be shaped as a gap or can be formed from bores lying one next to the other. The attachment component (11) can be fitted onto conventional spray guns in place of an air cap and can be screwed tight by means of a holding ring. <IMAGE>
