Jet flow alternator

A jet flow alternator for directing the flow of a fluid substance in a select direction comprising, in combination, an outer cylindrical shell, a pipe of lesser diameter than said shell extending axially through said shell and through which a substance flows, means at the ends of said shell closing the space between the shell and pipe to provide a cylindrical chamber between them, a plurality of superposed tubes mounted around said pipe, said tubes being shiftable with respect to each other and said pipe, a plurality of circumferentially and axially spaced apertures in said tubes and pipe, said apertures being aligned normally to provide fluid passageways, means to deliver pressurized fluid of greater pressure than in said pipe into said chamber for passage through said passageways into the interior of the pipe, and means to shift the tubes relative to the pipe and to each other to offset the apertures in the tubes with respect to the apertures in the pipe to direct the pressurized fluid entering the pipe through said passageways towards a selected end of the alternator.
