Abstract
A backflow preventer at the end of an injection molding worm has a pressure ring which abuts directly upon the worm and serves a shank of the valvehead which also bottoms in a bore upon the worm so that force transmission to the worm is over its entire cross section. The shank is surrounded by a blocking ring which can shift in its axial stroke between a position in which it abuts the head and a position in which it abuts the pressure ring, the axial stroke being adjustable by shims forming the floor against which the shank abuts within the bore of the worm.
