ABSTRACT:
Method and apparatus for dispensing material from a hand-held gun connected by a flexible conduit to a source of the material under pressure. The control of material flow is effected by a valve in series between the flexible conduit and the source of material, and hence remote from the gun, thereby to reduce the weight of the gun and to provide a gun that has no moving parts for controlling material flow. One or more orifices is provided in the handle of the gun for the continuous discharge of low pressure control air that actuates the valve or valves; and the selective opening or closing of the orifice or orifices by the hand or fingers of the operator, thus controls the valve or valves and hence the flow of material for materials to the gun. The invention is particularly useful for dispensing synthetic resins, which may require the provision of separate streams of resin, catalyst or hardening the resin, compressed air for atomizing the resin-catalyst mixture, chopped glass fiber, compressed air for actuating the glass fiber chopper, and solvent for flushing the mixing chamber of the gun.
