Centrifugal Expanders And Compressors Each Using Rotors In Both Flow Going From Periphery To Center And Flow Going From Center To Periphery Their Use In Engines Both External Heat And Internal Combustion. Means to convert radial inward flow to radial outward flow with less eddy currents

摘要

An engine feeds, at either the periphery or the center of one of the pumps, either compressed then heated air or products of combustion into centrifugal expanders in series. This invention is also 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 the use of combinations of centrifugal pumps used to form a multistage compressor or a multistage expander with at least one pump processing a flow of gas traveling from the vicinity of the axle toward the periphery of the pump and with at least one other pump processing the same flow of gas traveling from the periphery of this other pump toward the axle of this other pump. The invention also includes the use of either the above centrifugal multistage expander or the above centrifugal multistage compressor, or both, in an external heat engine or in a heat pump.
