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°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.

A mixing head for at least two reactive components comprising: a housing formed with a bore defining a mixing chamber and having an outlet for discharge of a reaction mixture; a control plunger displaceable in said bore from a position wherein said plunger is retracted from said outlet into a position wherein said plunger is proximal to said outlet thereby driving a reaction mixture from said mixing chamber out of said outlet; at least two nozzles which form a pair of nozzles in said housing juxtaposed with one another in a direction along the path of said plunger for impinging streams of respective interreactive components against one another to form said reaction mixture; a nozzle body carrying one of said nozzles and shiftable transversely of the direction of displacement of said plunger into said chamber toward the other of said nozzles; and means for advancing said body into said chamber into said path of said plunger and retracting said body from said chamber out of said path.
