摘要：

A gravity-fed spray gun assembly of the type having a nozzle assembly, a spray gun body assembly and a nozzle nut for adjusting the relative angular orientation of the nozzle assembly relative to the spray gun body assembly. The spray gun assembly includes a spray gun body assembly, a-fluid delivery assembly and a locking element. The fluid delivery assembly includes a rotatable element, a nozzle assembly and a fluid cup. The rotatable element is rotatably connected to the spray gun body assembly. The nozzle assembly is securely attached to the rotatable element. The nozzle assembly is maintained unable to rotate relative to the rotatable element unless a nozzle nut is adjusted. The nozzle assembly has a nozzle opening defining a nozzle axis. The rotatable element is rotatable about the nozzle axis. The fluid cup is securely attached to the rotatable element. A locking element cooperatively engages the spray gun body assembly and the fluid delivery assembly to securely lock the spray gun body assembly relative to the fluid delivery assembly at the desired relative angular orientation. The present invention obviates any requirement for loosening the nozzle nut to rotate the nozzle assembly relative to the spray gun body assembly when the fluid cup is rotated relative to the spray gun body assembly.
