Abstract: An applicator gun for dispensing hot melt adhesive comprises a hydraulic material supply hose connection, an electrical power cable connection, and a hanger bracket connection. The hose connection may be inverted, and the power cable and hanger bracket connections interchanged so as to provide the applicator gun with different orientation capabilities. The applicator gun may also alternatively accommodate four-finger and two-finger trigger members, and the gun may be connected to the hose connection so as to be movable in alternative modes comprising rotation around a single linear axis or universal movement within six degrees of freedom.

Abstract: A hot melt adhesive dispensing valve assembly comprises a removable inline nozzle filter which is mounted within the hot melt adhesive dispensing valve assembly at a position or location which is immediately upstream of the hot melt adhesive dispensing valve assembly nozzle. The filter member or component is interposed between the valve seat for the hot melt adhesive dispensing valve which is formed within the hot melt adhesive dispensing valve assembly adapter and the hot melt adhesive dispensing valve assembly nozzle which is threadedly mounted within the adapter.
