AIR SPRAY GUN IMPROVEMENTS IN NOZZLE AND AIRCAP

摘要

The feeder passages (22) in the aircap (20) of an air spray gun (10) are slots which are significantly wider than the horn exit holes (24). This construction makes centerline offset much more forgiving by providing a consistent intersection of the passages. The feeder passages (22) are also deeper in that they extent past the intersection point (26) again making them more forgiving of irregularities. Sealing and seating of the nozzle (18) to the fluid inlet (16) have also been improved over the prior art. In the instant invention, o-rings (28) seal the nozzle (18) to the fluid inlet (16) and allow the shoulder (18b) of the nozzle (18) to seat squarely on the spray housing (14) controlling angularity.
