Rotary roller motor (RRM)

A rotary combustion motor comprising:

• an engine block having an interior surface defining a cavity, an air intake port permitting air into the cavity, and an exhaust port releasing gas out of the cavity;
• a rotor passing through the cavity, the rotor comprising
• a rotary shaft;
• an offset circular lobe attached to the rotary shaft and housed within the interior cavity;
• an outer rotor contacting the interior surface of the engine block;
• and
• bearings between the outer rotor and the offset circular lobe;
• a combustion chamber having an inlet for fuel, a first opening to the cavity, and a second opening to the cavity, the first and second openings separated by a compression/power barrier urged against and maintaining contact with the outer rotor;
• a non-reversing compression barrier for selectively permitting air to pass through the first opening from the cavity to the combustion chamber;
• a compression hold barrier for selectively permitting combusted gases to pass through the second opening from the combustion chamber to the cavity;
• and
• an exhaust/intake barrier between the intake port and the exhaust port urged against the outer rotor,
• wherein the engine block interior surface, outer rotor, compression/power barrier and exhaust/intake barrier define a fluid pathway from the intake port through the first opening, the combustion chamber, the second opening, and the exhaust port, the fluid pathway being selectively blocked by the outer rotor rolling along the interior surface.
