A two stroke mechanism is described which has rotary moveable piston and cylinder-piston elements. The piston and cylinder-piston elements both rotate within a stationary body forming two variable volume chambers. The first variable volume chamber formed between the piston and cylinder-piston elements may serve as a combustion or compression chamber. The second variable volume chamber formed around the piston and cylinder-piston elements and within the stationary body may serve as a precompression chamber. Methods for balancing, sealing, intake, discharge and cooling such mechanisms are disclosed. The mechanisms are especially useful as internal combustion primer movers, external combustion prime movers, pumps and compressors.
