Abstract (en)

[origin: WO2016059492A1] A control system comprising: - a variable volume positive displacement rotary pump (2), in turn comprising: i) a stator (20) that is movable so as to determine a variation in the volume of the pump (2); ii) a first and a second thrust chamber (21, 22) for thrusting the stator (20) and designed to be filled with a fluid processed by the pump so as to regulate the movement of the stator (20); -a supply line (3) for supplying the fluid processed by the pump (2) to a load. -an element (4) that defines a localized loss in load, said element (4) being located along said supply line (3); The first and second thrust chambers (21, 22) are supplied upstream and downstream of said element (4) that defines a localized loss in load, respectively.
