ABSTRACT:
A positive displacement apparatus usable as a pump or motor or flowmeter comprises a first revolving vane rotatably disposed in a first cylindrical cavity wherein the edge of the first revolving vane sweeps on a circular cylindrical portion of the cylindrical wall of the first cylindrical cavity, and a second revolving vane rotatably disposed in a second cylindrical cavity wherein the edge of the second revolving vane sweeps on a circular cylindrical portion of the cylindrical wall of the second cylindrical cavity, wherein the rotating motions of the first and second revolving vanes are coupled to one another in such a way that the edge of at least one of the first and second revolving vanes sweeps on respective circular cylindrical portions of the cylindrical walls of the respective cylindrical cavities at all instances, whereby a fluid moving through the first and second cylindrical cavities providing a flow passage in series results in a rotating motion of the revolving vanes and vice versa.
