ABSTRACT:
A hand held spray gun including a gun body, a barrel and a nozzle assembly attached to the front of the barrel. A tubular retainer passes through a portion of the body and is threaded into a passage in the barrel to connect the barrel to the body. A fluid valve actuator extends from the body through the retainer and into the barrel passage for operating a fluid valve in the nozzle assembly. The retainer also functions as a guide for the valve actuator, holds a radial fluid seal for forming a sliding seal against the valve actuator and serves as a stop for a spring biased fluid seal between the valve actuator and the barrel.
