Abstract: A reversible reduction gear motor which is driven by a pressurized fluid such as air or a liquid is provided having a hollow recoil rotor, which engages a drive motor and which is mounted rotatably on a shaft which extends through the recoil rotor. This shaft, which extends through the recoil rotor, has a reduction gear mounted on one end which engages a pinion mounted on one end of the shaft of the drive rotor. The other end of the shaft, which extends through the recoil motor, has a pinion mounted on it which engages a second reduction gear, the axis of rotation of which is coincident with the axis of rotation of the drive rotor. The driving fluid is supplied by conduits disposed within the motor and is controlled so that it can be supplied to drive the rotors in either a forward or reverse direction.
