ABSTRACT:
A multi-purpose flow apparatus of the type which operates on the principle of volumetric displacement, has an internally helicoidal chamber rotatable about its center of gravity and having one of a constant or variable pitch and z.sub.k thread starts and an externally helicoidal spindle rotatable about an axis disposed at its center of gravity. The spindle has z.sub.o =z.sub.k +1 thread starts, the thread division thereof is z.sub.o /z.sub.k times the pitch of the chamber and the angular velocity of rotation of the spindle is z.sub.k /z.sub.o times that of the chamber.
