A device for feeding flowable materials, e.g., a mixture of inter-reactive components, into a mold cavity, has a mixing chamber opening directly into the mold cavity without constriction and a pair of inlets connected to respective supply lines for the components. A control member or plunger is provided in the reaction chamber to close its outlet flush with a mold surface and is provided with grooves in a closed condition of the slider which create recirculation paths for the components when they are not fed to the mixing chamber.
