Patent ID: 8210150

Claim:
A motor comprising: a combustion chamber; a central rotor disposed within the combustion chamber, the central rotor defining an intake chamber, an explosion chamber, and an exhaust chamber within the combustion chamber; a shaft engaging the central rotor longitudinally and having a proximal portion and a distal portion extending from the combustion chamber in opposite directions; and a proximal rotor and a distal rotor coupled to the shaft in symmetrically opposite positions, the proximal and the distal rotors having passages defined thereon to receive at least some exhaust gas exiting the combustion chamber and to impart a vertical motion to the at least some exhaust gas, wherein the at least some exhaust gas in the proximal and the distal rotors is directed to an interspace between the shaft and a housing of the motor, thereby forming a proximal pneumatic bearing and a distal pneumatic bearing between the shaft and the housing, the proximal and the distal pneumatic bearings maintaining the shaft in suspended position during operation of the motor.
