Abstract
A gun for dispensing a plural component system includes a housing having appropriate connections to a pressurized air supply and pressurized first and second component storage reservoirs. Within the housing are located first and second component feed ports, each having a control valve located in its interior. A valve carrier member is movably located in the housing and is moved by a trigger. The first and the second valves are connected to and moved in response to movement of the valve carrier member. The gun includes a gas passage having a gas valve located therein. The gas valve is also connected to and moves in response to the valve carrier. At the forward end of the housing is a static mixing chamber which has a discharge outlet as well as inlets leading to both of the component feed ports and to the air passage. When the valve carrier is in a first position pressurized air is introduced into the mixing chamber which purges the mixing chamber. When the valve carrier is in a second position the components of the plural component system are discharged from the respective component feed ports into the mixing chamber and out of the discharge outlet.
