Abstract
A mixing head for two reactive components, e.g. the components of a settable synthetic resin mixture, comprises a mixing chamber in which a plunger is shiftable to block and unblock the nozzle orifices and drive the reaction mixture from the chamber through an outlet. At least one of the nozzles is carried on a readily shifting slider which cooperates with a similarly shiftable obturating member to define a small premixing chamber, as desired, and deflect the mixture through at least 90.degree. within the mixing chamber. This system is especially effective for the mixing of reactive components which have hitherto been found to be difficult to mix with conventional mixing heads.
