Abstract
A hydraulic motor comprises vanes slidable axially in lodgings of a rotor against a continuous stator bottom surface. The motor works with a hydrostatic transmission of power applied to rolling stock. The bottom surface has recesses formed therein on movable elements of stator wherein a constant pilot pressure is fed to said movable elements and the motor is a self regulated variable capacity motor since the capacity thereof results from the depth of the recesses due to the opposition of two forces, one from the pilot pressure and the other from a pressure coming from the resisting torque.
