Claims14
An adjustable spray nozzle for use with a spray gun, said spray gun being adapted for hydraulically atomizing and spraying liquids and including conduit means communicating with a source of liquid under pressure, said adjustable spray nozzle comprising:
- a. a spray tip housing including means for securing said housing to said spray gun;
- b. a fluid bore in said housing communicating with said conduit means and terminating in a spray opening in said housing having substantially sharp edges to thereby permit the transference of pressurized liquid from said source to said spray opening;
- and
- c. valve means included in said spray tip housing for varying the size of said spray opening from a closed position to a fully open position including all intermediate positions therebetween to thereby adjust the spray of liquid issuing from said spray opening.
An adjustable spray nozzle for use with a spray gun, said spray gun being adapted for hydraulically atomizing and spraying liquids and including conduit means communicating with a source of liquid under pressure, said adjustable spray nozzle comprising:
- a. a spray tip housing including means for securing said housing to said spray gun;
- b. a valve bore extending partially through said housing;
- c. a groove formed in said housing and intersecting the side wall of said valve bore to thereby form an opening therein having substantially sharp edges;
- d. A fluid bore in said housing communicating with said conduit means and said valve bore to thereby permit the transference of pressurized liquid from said source to said valve bore;
- e. a valve stem extendable into said valve bore and having a bottom face defining a substantially sharp edge with said stem;
- and
- f. means for adjustably moving said valve stem in said valve bore to vary the opening in said valve bore and thereby defining a spray opening having substantially sharp edges.
