Improvements in hydraulic-pneumatic motors, characterized in that each motor is constituted by a crankcase formed by a hollow cylindrical body, provided at one end with a circular cover to which a cam is fixed and on the other with a cap in the form of a crown circular to allow the passage of the axis of the rotor, which is formed by a hollow cylindrical piece opened by one of its bases, while the other emerges the shaft, said cylinder presenting a series of longitudinal openings in which they are housed, shaped radially displaceable as many vanes tractioned by respective springs to their position of contact with the cam, forming as many chambers of variable volume between the crankcase and the rotor as vanes are arranged in the rotor.
