Abstract
A rotary engine is powered by pressure from gas or fluids. At least two pistons are positioned within a stator having an annular chamber. Pressure is provided between the pistons, which provides a force to push one piston relative to the other piston. One or more dogs control the travel of the pistons. Power is harvested from the pistons.
