Abstract
A mixing head for mixtures of reactive components, e.g. two-component synthetic-resin systems to be discharged into a mold, in which the orifices for the two components open into a mixing chamber and can be selectively blocked or unblocked by a plunger or piston which serves to drive the mixture out of the chamber. According to the invention a blocking body (baffle barrier) is provided on a connecting rod which extends through the plunger and, in a retracted position of the latter, is located in the path of the jets of the reactive components emanating from the orifices.
