Abstract
Apparatus for the production of homogeneous material or foam from a plurality of components. A three-way valve is communicated with supply tanks for the components by pipes having pumps interposed therein. The valve cock has a mixing chamber therein and an outlet for discharge of the mixed components to a mold, and is provided with passageways so that depending on the position of the cock the components can be delivered to the mixing chamber or to return lines for the individual components which lead to the intake side of the pumps. The components are constantly pumped, passing either to the mixing chamber or to the return lines.
