Abstract (en)

[origin: DE4341607A1] The plunger (4) delivers the viscous material from a loading chamber (6) fitting closely round it into a transporting cylinder (8). Any solid particles protruding through the cylinder inlet are sheared off by the forward end of the plunger as it passes into the cylinder. There can be a cutting edge round the forward end of the plunger, and the solid particles can be mixed with viscous material or liquid.A rotary movement can be superimposed on the sliding movement of the plunger. Where a predetermined pressure of the medium driving the plunger is exceeded, the latter can be retracted and then thrust forward again.
