Method for producing mechanical work in a conical helix turbine

摘要

A method of producing mechanical work includes swirling a compressed working medium and expanding it to produce mechanical work in an actuating device 1 which has a fluid pathway in the form of a conical helix the projection of which on a plane positioned at an angle to the axis of rotation is a curve having at least two breakpoints. Preferably a segment of the curve is a hyperbolic spiral and the lead of the conical helix is variable. The working medium may be discharged from the actuating device by at least two jets 6 into a closed shell 4 in the form of a blade turbine.
