Abstract: A hydraulic motor having radial pistons, and comprising a cam, a cylinder block and a distributor. The cylinders of the cylinder block are connected to communication orifices (32A) situated in a communication face of the cylinder block, while the distributor has a distribution face in which distribution orifices (21A, 23A) are provided that are suitable for communicating with the communication orifices for rotating the motor. The cam is provided with a plurality of lobes (50, 50′), each of which has two ramps (51, 52), each ramp corresponding to a distribution orifice (21A, 23A). The edge of each of at least certain communication orifices (32A) has at least one notch (54A, 54B) suitable for establishing a small section of communication with a distribution orifice. The invention applies in particular to hydraulic motors having radial pistons for which the ratio between the number of cylinders and the number of cam lobes is in the vicinity of 1.

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.
