Abstract
A dispensing gun assembly including a gun body having a handle and a housing attached to the gun body. The housing includes first and second fluid passageways and first and second valve receiving bores. The fluid passageways are segregated from one another within the housing. First and second valves are received in the valve receiving bores. Each valve has open and closed positions and the valves move within the valve receiving bores when changing between the open and closed positions. A trigger member controllably contacts the valves and a nozzle assembly is connected to the housing.
