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.
