Abstract

Improvements in motors powered by pressurized hydraulic fluid, or air. The mechanism comprises: two rotors, interconnected by pistons which are bent into identical angles, and are inserted into the corresponding receiving holes of both rotors. The pistons can be pressurized in one, or in both rotors simultaneously, thereby varying the torque output and speed of the motor.
