摘要： The hydraulic machine comprises a cam (4) and a cylinder block with pistons (14) collaborating with the lobes of the cam, which lobes each have two ramps (50A, 50B) extending between top dead centre and bottom dead centre (PH, PB) arcs. The cylinders are connected alternately to a supply and to an exhaust, according to sequences separated by switchover phases comprising a phase of isolation with respect to the main, supply and exhaust, ducts. The angular position of the start or end of at least one first phase of isolation with respect to the corresponding dead centre arc differs from the angular position of the start or end of at least a second phase of isolation with respect to its corresponding dead centre arc, these dead centre arcs both being top dead centre or bottom dead centre arcs.
