Abstract
Frequent cleaning, maintenance, and or replacement of spray guns is necessary for good performance, but cleaning is often neglected because of difficulty in reaching the crucial parts to be cleaned. The spray gun of this invention has a fluid flow assembly which may be readily removed to facilitate cleaning. In addition, this spray gun has an external fluid flow assembly packing gland adjustment nut, which allows frequent convenient adjustment of the packing gland without disassembly of the spray gun. This allows the user to maintain free movement of the needle valve shaft while preventing leakage of fluid into the spray gun body.
