摘要： A replenishing device for a closed circuit comprising at least one hydraulic motor and at least two main pipes which are connected to the pump to provide respectively the feed and the discharge for the motor. The device comprises a replenishing selector suitable for putting the main pipe that is at the lower pressure in communication with a valve which itself communicates with an atmospheric pressure reservoir. The replenishing selector and the valve are united in the same replenishing valve unit having an inlet suitable for being connected to the main pipe that is at the lower pressure, and an outlet which communicates continuously with the atmospheric pressure reservoir. The valve is suitable for causing the inlet to communicate with the outlet when the pressure in said main pipe reaches a given pressure threshold.

摘要： 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.
