Abstract

The assembly includes an oil accumulator (23) to cause second- stage (rapid) advancement of an injection piston (3) and, in lieu of the usual piston multiplier there is provided a further oil accumulator (29), which is put into communication with the injection cylinder (1) through suitable valve means (34) at the end of the second stage of advancement of the injection piston (3).
