Description:
This rotary steam engine design avoids the use of "cam-actuated reciprocating elements, which, from their very nature, are inefficient and short lived." Instead, the engine uses rotary pistons that move with an irregular angular velocity; the intake and exhaust ports are covered and uncovered by the movement of the pistons.
