Patent ID: 10072665

Abstract:
An engine using centrifugal pumps to form a centrifugal multistage reverse compressor with flow alternating inward and outward in series. It is fed, at either the periphery or the center of one of the pumps, by either compressed then heated air or by products of combustion. This invention also includes a set of related inventions, comprising a group of flow guides to convert radial flow to axial flow and a group to convert axial flow to radial flow and the combination of those flow guides. The invention also includes a multistage centrifugal compressor using combinations of centrifugal pumps with alternating pumps having inward flow of gas traveling from the periphery to the vicinity of the axle and having outward flow of gas traveling from the vicinity of the axle to the periphery. The invention also includes the using the above in an external heat engine or heat pump.
