System for driving a hydraulic member

A system for driving a member by means of a hydraulic circuit, comprising:

• a hydraulic energy source adapted to deliver a pressure in the hydraulic circuit,
• a drive member, comprising:
• a casing with a first casing office and a second casing orifice that are adapted to define an intake and a discharge of the casing,
• a primary hydraulic machine adapted to be supplied by the hydraulic energy source, the primary hydraulic machine being housed in the casing and having a first hydraulic machine orifice and a second hydraulic machine orifice,
• wherein the drive member comprises a pressure booster integrated into the casing,
• said pressure booster being adapted to selectively raise the pressure, such that the pressure difference between the two orifices of the primary hydraulic machine is greater than the pressure difference between the two orifices of the casing.
