Apparatus for the production of a reaction mixture

摘要

The present invention relates to an apparatus for the production of a solid-forming or a foam-forming reaction mixture from at least two flowable components, the apparatus comprising a mixing head, at the outlet opening of which is connected at an angle a filling tube in which an ejection piston which is designed as a piston head and having a piston rod of a smaller diameter is positioned, the rear neutral position of the piston head being located upstream of the outlet opening of the mixing chamber, characterized in that an introduction slit is provided in the filling tube between the rear neutral position of the piston head of the ejection piston and the outlet opening of the mixing chamber and a delivery device for cleaning platelets is associated with the introduction slit.
