Rotary engine and compressor

An internal combustion rotary engine comprising:

• a casing forming a cylindrical chamber and having a number of holes and ducts as part of the cooling- and the lubrication systems, end covers that support the main engine shaft and are securely fixed on the sides of the casing, a rotor as a means for delivering power including piston chambers (replacing cylinders in conventional engines), rotationally reciprocating pistons in piston chambers to convert the expansion of combustion gas to rotational motion, piston pins allowing pistons to rotate around the pin axes, planet gears mounted on one or both side(s) of the rotor by fixing supports and piston rods that synchronize the rotation of both the pistons and the said planet gears where the planet gears are meshed with a sun gear(s) fixed on one or both side(s) of the casing on the engine block and the rotation of the planet gears around their own axes at the combustion stroke causes them to move on the sun gear(s) and causes the said rotor to rotate around the main shaft axis.
