ABSTRACT:
An airless spray paint gun having an improved swirl valve which is less susceptible to erosion and reduces the amount of sputtering in the paint spray. The spray paint gun includes a gun assembly including a handle, a motor, and a switch for controlling the motor. A pump subassembly mounted to the gun assembly includes a pumping chamber having a discharge end with a beveled seat, a piston mounted within a pump housing and driven by the motor for pumping paint from the container through the discharge end of the pumping chamber, and a swirl valve mounted within the discharge end of the pumping housing. The swirl valve includes a valve body having first and second opposite sides, three paint swirl apertures extending through the valve body between the first and second opposite sides, a beveled seat-engaging surface on the second side of the valve body formed of an elastomeric material co-molded with the valve body. The elastomeric material is softer than the material of the valve body.
