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.
Claims5
In a multi-purpose flow apparatus of the type which operates on the principle of volumetric displacement, the improvement comprising a casing having an inlet and an outlet disposed along a given line, an internally helicoidal chamber member rotatable about its center of gravity parallel to the given line and having z.sub.k thread starts:
- an externally helicoidal spindle, and means mounting the spindle for rotation about an axis disposed at its center of gravity and parallel to the given line and comprising bearings and a fluid fluid flow guide cone for each bearing at the inlet and the outlet, wherein the spindle has z.sub.o =z.sub.k+1 thread starts, the thread division thereof is z.sub.o /z.sub.k times pitch of the chamber member and the angular velocity of rotation of the spindle is z.sub.k /z.sub.o times that of the chamber member.
