ABSTRACT:
A uniflow steam engine of the multi-cylinder type wherein the cylinders are rotatably mounted within a jacket having a sinusoidal cam track therein. Extending through slots, the ends of which are the exhaust ports in the cylinders and into the cam track are cam followers which are mounted on the pistons for reciprocable movement therewith. At the head end of the cylinders there are apertures which rotate with registered cutouts in superimposed valve rings that control the flow of steam from manifolds at the head ends of each of the cylinders into the cylinders as the cylinders rotate. By adjusting the relative position between the valve rings, the length of time of steam introduced on each cycle may be adjusted and by concomitantly rotating both valve rings, the initial time for introduction of steam may be adjusted to alter lead or reverse torque.
