System for driving a member (10) by means of a hydraulic circuit, comprising: a hydraulic energy source (100) adapted to deliver a pressure in the hydraulic circuit, a drive member (200), comprising: a casing (210) with a first orifice (212) and a second orifice (214), a primary hydraulic machine (230) housed in the casing (210) and a pressure booster (300) integrated into the casing (210), said pressure booster (300) being adapted to selectively raise the pressure, such that the pressure difference between the two orifices (232, 234) of the primary hydraulic machine (230) is greater than the pressure difference between the two orifices (212, 214) of the casing (210).
