ABSTRACT:
A screw extruder and positive displacement wave pump assembly for plasticating or melting solid plastic material or the like, including an extruder screw member in an elongated cylindrical barrel having an upstream end and a downstream or discharge end, the screw being rotatably housed in portions of the barrel adjacent the upstream end. The screw has a helical thread of plural turns integral with the core of the screw having a minimum clearance to the barrel for feeding the plastic material along the screw from its feed end to its discharge end. A positive displacement wave pump is located in the barrel near the outlet end having a stator frame and a rotor member rotatable therein coupled to and driven by the screw, the rotor member having an outer surface of developed helical coutour providing a plural turn helical thread of wide rounded form to position a stack of slidable sealing discs guided for diametric sliding movement by the rotor passing therethrough to form a series of pumping pockets which progress longitudinally through the pump section.
