    摘要： The instant invention is directed to a mixing head for mixing at least tw flowable components which preferably form a foam during their reaction. The mixing head comprises a housing, in which a guide bore for a discharge piston is positioned, one section of this guide bore being designed as a mixing chamber, into which nozzle openings of injection members, positioned equidistant around the housing, discharge. In the mixing position of the discharge piston, the mixing chamber is bounded by the leading edge of the piston, with an outlet opening being provided opposite the piston. A choke member, which adjoins the mixing chamber and is movably positioned in a guide recess extending perpendicular to the guide bore and transversely beyond the axis or plane of the injection members, has a passage, the cross section of which corresponds to the cross section of the discharge piston such that the piston may enter this passage in its cleaning position. Further, the guide recess and the choke member have sections of reduced cross-sectional areas toward the mixing chamber, these sections extending into the mixing chamber, but leaving the mixing chamber clear.
