ABSTRACT:
The pressure-regulating system for a hydraulic circuit, comprises at least one generator (22) of fluid under pressure, a hydraulic motor (20) and a reservoir (24) of fluid under low pressure. It further includes a solenoid valve controlled by a computer and comprising an electrical coil (1) and a sliding magnetic core (3) controlling a slide (7) sliding in a bore provided in a body (9). The slide (7) defines two chambers (11, 15) arranged on either side of the slide (7) in the bore. The slide (7) comprises a hydraulic cell (26) determining a reaction force opposing the force generated by the coil (1), the cell (26) being connected to one of the chambers (11, 15) as long as the solenoid valve is not energized, while it is connected to the hydraulic motor (20) after energization. An elastic mechanism (13) returns the slide (7) and the core (3) to the rest position.
