    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 zk thread starts and an externally helicoidal spindle rotatable about an axis disposed at its center of gravity. The spindle has zo=zk+1 thread starts, the thread division thereof is zo/zk times the pitch of the chamber and the angular velocity of rotation of the spindle is zk/zo times that of the chamber.
