Abstract
Apparatus for and method of supplying viscous blends, casting resins for example, of two or more components that react and cure when blended, preferably in a vacuum. There is one holding tank for each component. There is a set of flow controls downstream of each holding tank. There is check valve downstream of each set of flow controls. There is a line downstream of each set of flow controls or of each check valve. Blenders communicate with each line. An injector downstream of each blender supplies the blend to a compression-setting mold. The line leading out of each holding tank and through the flow controls and check valve extends past each blender and back into the tank, accordingly constituting a closed loop that begins and ends at the tanks. The loops extend through FORWARD/DIVERT valves with one intake and two alternatively opening and closing outlets. One outlet forwards the component on through its loop. The other outlet diverting it out of the loop to one of the blenders.
