Elliptic piston type dual-drive-rotor explosive motor

The invention discloses an elliptic piston type dual-drive-rotor explosive motor. Based on the structure basis of an elliptic piston type rotor explosive motor declared by an applicant originally, a second coaxial drive motor with the same plane mechanical specification is additionally arranged, and two drive rotors form a longitudinal crossed overlapped coaxial assembling relationship; because main shafts of two elliptic wheel piston type drive rotors can perform four times of explosive drive actuating processes when rotating directionally for one circle, and the work of the explosive motor is equivalent to the work of a four-stroke type eight-cylinder explosive motor, the mechanical performance of output power of the rotor explosive motor is improved. Based on the structure of the double-driven-rotor explosive motor, two supercharge rotors with the equal plane specification are respectively arranged additionally, the content of high-pressure gas in a compressed gas storage chamber of two driven rotors and the explosive drive efficiency of the motor are doubled, so that the explosive drive efficiency of the dual-drive rotor explosive motor is improved.
