ABSTRACT:
A heated handgun and hose assembly adapted to dispense heated liquids, such as hot melt adhesives, coatings, sealants, caulks and various other materials. The handgun and hose assembly includes a gripping portion and an actuating lever extending generally in line with the hose. The actuating lever operates a valve integrated with the nozzle to selectively allow or prevent the flow of liquid through the nozzle. A connection between the actuating lever and the nozzle limits the stroke of the valve and the travel of the actuating lever. A hose heater and multi-layer insulating materials wrap around the body of the valve as well as along the entire length of the hose. A membrane switch is incorporated into the actuating lever for applications utilizing an electrically-operated pump. The valve includes a suck-back feature to improve liquid cut-off and to prevent drooling of liquid from the nozzle outlet.
