ABSTRACT:
A rotary machine, having a casing and a rotor rotatable eccentrically in the casing to define an eccentric annulus divided into compartments by vanes, to function either as a compressor or an expansion engine has the vanes pivoted at the rim of the rotor and driven by a mechanical coupling to their operative positions. The vanes are driven by cranks lying in planes outside but parallel to the planes in which the vanes operate. The vanes operate with a minimal clearance between vane tip and casing in order, ideally, to provide zero friction at the vane tip.
A power system is disclosed in which air is compressed, heated in a flame tube, expanded under volume confined conditions in a rotary machine as described to an intermediate pressure, and expanded to ambient under volume confined conditions in another rotary machine as described. The machine may drive auxiliaries in a vehicle.
