ABSTRACT:
A centrifugal positive displacement device is presented. It is believed that this is the first type device which has the advantages of both a centrifugal pump and a positive displacement pump without any substantial disadvantages. The device comprises a casing similar to that of previous centrifugal casings disposed around an impeller smaller than prior art centrifugal impellers and having cavities in the outer surface thereof. On each side of each cavity is coupled a flexible loop. In operation, as it passes the cam, the flexible loop is filled with incoming fluid which is then compressed out as the cam is approached near the discharge port.
