Abstract
A deflector-mixing head for a reaction molding machine, comprises a mixing chamber with a control piston for regulation of component inflow, an overflow chamber is arranged downstream from the mixing chamber in a perpendicular position thereto and provided with a cleaning piston which controls the opening and closing of the mixing chamber side of the inlet of the overflow chamber, wherein an improved mixing quality is obtained by arranging a connection chamber substantially parallel to the axis of the overflow chamber, between the mixing and overflow chambers and provided with deflector elements positioned in the flow path between the inlet and the outlet side of the connecting chamber, and by arranging a displacement piston parallel to the cleaning piston for emptying the connection chamber.
