Power module

Abstract

Abstract A power module for providing continuous rotational torque without direct contact between the propellant and module rollers. A plurality of flexible tubes are positioned within helical grooves in the inner surface of a cylinder casing. A rotor assembly having a plurality of rollers is positioned within the casing mounted for rotation against the inner surface and driving a power shaft. The rollers and tubes are in angularly disposed contact with each other, preferably at substantially right angles. Pressure is applied to the tubes causing them to uniformly expand along the grooves and inwardly of the inner surface of the cylinder, driving the rollers. The chordal distance between the rollers and the location of the tubes along the inner surface of the cylinder is crucial and designed so that as the roller is forced off the edge of one tube, at the exit end, the succeeding roller is just about ready to make contact with the entrance end of the particular tube. As the first roller leaves the tube, the force causing a pressure build-up behind the roller is removed and fluid can be expunged therefrom. There is sufficient inertia in the succeeding roller to cause it to move onto the entrance end of the tube and the continuing fluid entering the tube immediately causes a pressure build-up behind the roller and the process begins again. When the tubes have been completely expanded, the inertia within the rollers carries them until they are positioned just ahead of the next collapsed tube, and the procedure is repeated.
