Description

[Brief explanation of the drawing]

The attached drawings show one embodiment of the present invention, and FIG. 1 is a cross-sectional view, FIG. 2 is a cross-sectional view taken along line A--A in FIG. 1, and FIG.
The figure is a sectional view taken along line B-B of Figure 1, Figure 4 is a partial perspective view, and Figure 5 is a graph showing the relationship between the flow rate of pressurized air for pattern adjustment, pattern width, and cross-sectional shape of paint flow. It is. 1: Gun body, 2: Paint spout, 5: Cap, 8: Retainer, 25: Pressurized air supply path, 35:
Air outlet for tail extinguishing, 36: Branch passage for tail extinguishment, 48: Throttle valve, 53: Air outlet for pattern adjustment, 55: Branch passage for pattern adjustment, a: Paint flow, b: Tail, R: O-ring .

Claims (1)

[Scope of utility model registration request] A nozzle retainer attached to the front end of the gun body has an air flow path opened on the outer circumferential surface and front end face, each communicating with two pressurized air supply holes opened on the front end face of the gun body, and the nozzle retainer is fitted into the retainer. The inner periphery of the cap communicates with one air flow path opened on the outer periphery of the retainer to eliminate tails generated on both sides of the paint flow jetted in a fan-shaped pattern from a nozzle protruding in the center of the cap. The inlet of the tail extinguishing air outlet for ejecting pressurized air is opened, and the inner end surface of the cap communicates with the other air flow path opened at the front end surface of the retainer, thereby forming a pattern width of the paint flow. The inlet of the pattern adjusting air ejection hole that ejects pressurized air to adjust the air flow rate is opened, and an O-ring that seals between the two air flow paths is fitted to the outer periphery of the retainer that fits into the cap. A unique airless painting spray gun.
