Abstract: The invention relates to a hydraulic motor having an undulating cam and at least one large and one small selectable operating cylinder capacity. In the motor, cylinder feed orifices (41a, 42a) are distributed around the circumference of a circle about the axis of rotation (5), and the small cylinder capacity corresponds to an irregular angular distribution of active cylinder orifices (41a) which continue to be fed. This configuration makes it possible to provide a constant velocity motor with at least two different cylinder capacities and which is mechanically long-lasting.
