A loading and discharging circuit (12) selectively connects the reservoir to a pressure source (P) for loading, or to a tank (T) for discharging. The circuit includes a 3/3-way proportional valve (14) with a control piston (16) movable from a loading position in which the reservoir is connected to the pressure source, to a release position in which the reservoir is connected to the tank, where the piston is actuated by pressure of the reservoir or the pressure of the working line.",
