Hydraulic system for a utility vehicle, the said system comprising: - a variable-output pump, - at least one hydraulic receiver connected to the delivery orifice of the pump by a pressure line (10, 10'), - a flow restrictor device arranged in the pressure line between the pump and the hydraulic receiver, the said restrictor device being regulated to the control value of the said hydraulic receiver, - a control device set to a pressure value (ΔpLS), the said control device adjusting the delivery pressure of the pump as a function of a load pressure and of a set pressure (ΔpLS), - a regulating line allowing the load pressure to be transmitted to the control device, the said load pressure being a load pressure different from the actual load pressure (Pu) of the hydraulic receiver when a demand is placed on the latter, - a corrector device configured to control the control device with the load pressure different from the actual load pressure (Pu) of the hydraulic receiver, the said corrector device consisting of a directional control valve with two-position (I, II) operating slide and set spring, the said directional control valve comprising at least one outlet orifice connected to the control device by the regulating line, characterized in that: - the operating slide comprises a second inlet which is connected to the outlet orifice when the said slide is in a first position; and a first inlet which is connected to the said outlet orifice when the said slide is in a second position, the set spring being arranged in such a way that the said slide has a tendency to position itself in the first position, - a first end of the operating slide is subjected to the actual load pressure (Pu) at the outlet orifice of the flow restrictor device and to the pressure of the set spring, - a second end of the operating slide is subjected to the pressure (P LS) at the inlet orifice of the flow restrictor device or to the load pressure different from the actual load pressure (Pu), the said different load pressure being the pressure at the outlet orifice of the said slide. - a variable-output pump, - at least one hydraulic receiver connected to the delivery orifice of the pump by a pressure line (10, 10'), - a flow restrictor device arranged in the pressure line between the pump and the hydraulic receiver, the said restrictor device being regulated to the control value of the said hydraulic receiver, - a control device set to a pressure value (ΔpLS), the said control device adjusting the delivery pressure of the pump as a function of a load pressure and of a set pressure (ΔpLS), - a regulating line allowing the load pressure to be transmitted to the control device, the said load pressure being a load pressure different from the actual load pressure (Pu) of the hydraulic receiver when a demand is placed on the latter, - a corrector device configured to control the control device with the load pressure different from the actual load pressure (Pu) of the hydraulic receiver, the said corrector device consisting of a directional control valve with two-position (I, II) operating slide and set spring, the said directional control valve comprising at least one outlet orifice connected to the control device by the regulating line, - the operating slide comprises a second inlet which is connected to the outlet orifice when the said slide is in a first position; and a first inlet which is connected to the said outlet orifice when the said slide is in a second position, the set spring being arranged in such a way that the said slide has a tendency to position itself in the first position, - a first end of the operating slide is subjected to the actual load pressure (Pu) at the outlet orifice of the flow restrictor device and to the pressure of the set spring, - a second end of the operating slide is subjected to the pressure (P LS) at the inlet orifice of the flow restrictor device or to the load pressure different from the actual load pressure (Pu), the said different load pressure being the pressure at the outlet orifice of the said slide.
