Abstract
Improved spray guns each have a spray head assembly comprising separate but interconnectable elements including a fluid nozzle, a fluid inlet fitting, a fluid nozzle retainer, an air nozzle and an air cap. The elements mount on an annular extension at a forward end of the gun body without any threaded attachment to the body, and because they are separate the fluid nozzle and fluid inlet fitting may conveniently be manufactured of a corrosion and wear resistant material to protect the same from fluid flowing therethrough. Also, the air cap threads onto the fluid nozzle retainer and not the gun body, so there is no danger of damaging any threads on the body which could otherwise require its replacement.
Claims19
A spray gun having a gun body and a spray head assembly carried at a forward end of said body for emitting an atomized spray of fluid, said spray head assembly comprising a fluid inlet fitting separate from said gun body and having a passage therethrough connectable at one end with a supply of fluid;
- a fluid nozzle having a passage therethrough terminating at one end in a fuid outlet orifice;
- a fluid nozzle retainer detachably connected with said fluid inlet fitting and said fluid nozzle for supporting the same with opposite ends of said passage in communication, whereby fluid introduced into said one end of said inlet fitting passage flows through said passages for being emitted from said orifice;
- air emitting means at said one end of said fluid nozzle for emitting air for flow against fluid emitted from said outlet orifice, said air emitting means being detachably connected with said fluid nozzle retainer;
- and a member integral with and extending from said forward end of said gun body, said inlet fitting and fluid nozzle retainer compressibly capturing said member therebetween without threaded connection therewith when the same are detachably connected to mount said spray head assembly on said member at said forward end of said gun body.
A spray gun hving a gun body and a spray head assembly carried at a foward end of said body for emitting therefrom an atomized spray of fluid, said body having a downwardly depending generally annular extension at said forward end and said spray head assembly comprising a fluid inlet fitting separate from said body and having a passage therethrough connectable at one end with a supply of fluid, a portion of said inlet fitting including an opposite end of said passage extending forwardly into said annular extension;
- a fluid nozzle retainer, a portion of said fluid nozzle retainer extending rearwardly into said annular extension into detachable threaded connection with said inlet fitting portion, said inlet fitting and said fluid nozzle retainer compressibly capturing said annular extension therebetween without threaded connection therewith, whereby said annular extension mounts the same on said forward end of said gun body;
- a fluid nozzle having a passage therethrough terminating at a forward end in a fluid outlet orifice, said fluid nozzle being detachably threadably connected with said fluid nozzle retainer with a rearward end of said fluid nozzle passage in communication with said opposite end of said inlet fitting passage, so that a path is established for a flow of fluid from said one end of said inlet fitting passage to and through said fluid nozzle outlet orifice;
- and air emitting means at said forward end of said fluid nozzle for emitting air for flow against fluid emitted from said outlet orifice.
