<p>The invention comprises at least one generator (22) of pressurised fluid, a hydraulic motor (20) and a reservoir (24) of fluid at low pressure, and includes a solenoid valve driven by a computer and comprising an electric coil (1) and a sliding magnetic core (3) controlling a slide valve (7) sliding in a bore provided in a body (9), the slide valve (7) delimiting two chambers (11, 15) arranged on either side of the slide valve (7) in the bore. According to the invention, the slide valve (7) comprises a hydraulic enclosure (26) defining a reaction force opposing the force generated by the coil (1), the enclosure (26) being connected to one of the chambers (11, 15) while the solenoid valve is not excited, whilst it is connected to the hydraulic motor (20) after excitation, an elastic means (13) returning the slide valve (7) and the core (3) into a rest position. <IMAGE></p> |
