Paint gun with co-molded swirl valve

A swirl valve for a spray paint gun comprising:

• a valve body having a discharge side and an inlet side, and formed of a relatively hard material;
• a plurality of paint swirl apertures extending through the valve body between the discharge and inlet sides;
• a beveled seat-engaging surface on the inlet side of the valve body;
• and
• a relatively soft elastomeric material layer co-molded with the valve body to form a beveled surface thereon.

An improved swirl valve and airless spray paint gun assembly comprising:

• a motor, and
• a paint container;
• and
• a pump subassembly including:
• a pump housing in fluid communication with the paint container and having a beveled seat at a discharge end of the pump housing,
• a piston mounted within the pump housing and driven by the motor for pumping paint from the container through the discharge end of the pumping housing, and
• a swirl valve mounted within the pump housing and including:
• a valve body having a discharge side and an inlet side, and formed of a material characterized by a first hardness value,
• a plurality of paint swirl apertures extending through the valve body between the discharge and inlet sides,
• a layer of elastomeric material co-molded with the valve body and forming a beveled surface on the valve body, the elastomeric material characterized by a second hardness value which is less than the first hardness value.
