ABSTRACT:
A device for mixing and dispensing a pair of flowable materials includes a housing containing a pair of control valves for controlling the flow of the two materials into a mixer tube mounted on an outlet end of the housing. The mixer tube contains a mixing element within the bore of the tube. A control device such as a pneumatic piston, moves a shaft which is connected to the mixing element, to move the mixing element linearly axially within the tube to prevent the leakage of materials from within the tube after the control valves on the housing are moved to a closed position. An air motor may be connected to the shaft for rotating the mixing element within the tube to enhance the mixing of the materials moving therethrough.
