Abstract
A rotary engine is disclosed having a rotor and rotor housing for mounting therewithin said rotor for rotation within an inner wall of the rotor housing, a gap between the rotor and the inner wall of the rotor housing defining an engine compartment. A plurality of telescopic sealing blades which can elongate and shorten with respect to the rotor are attached, respectively at positions substantially equally spaced on the circumference of said rotor so that the sealing blades elastically contact to the inner wall of the rotor housing, the sealing blades sliding along the inner wall of the rotor housing during the rotation of the rotor and separating the engine room in an airtight manner so that the suction of fuel gas, its succeeding compression and the exhaust of burnt gas are carried out. The engine has a compression chamber and an expansion chamber, defined by two adjacent sealing blades, respectively. In an overexpansion rotary engine, a volume of the expansion chamber is greater than a volume of the compression chamber.
