ABSTRACT:
A dispensing gun for fluent products such as viscous adhesives and sealants. The gun includes a removably mounted nozzle and fittings for attachment to a product source such as a can or a hose. A valve body has product inlet and outlet passages with flow being controlled therethrough by a valve that includes a nose portion seated in the valve body, and a rod that extends through the nose portion of the valve and seats on tapered surfaces inside the end of the nozzle. The valve contains a shrouded internal spring biasing the valve to a closed position. A trigger engages the yoke carrying the valve and the valving rod and moves the yoke so that the rod and valve move between open, closed and intermediate positions. In one preferred form, the valving rod may be adjusted between positions wherein more or less product is dispensed in response to full trigger movement.
