Abstract
The device comprises a replenishing valve () having an opening control chamber suitable for being connected to a main duct () of the circuit, and a closing control chamber, the pressure in said chambers making it possible to cause the moving member of the replenishing valve to move so as either to connect or not to connect the main duct to which said valve is connected to a pressure-free reservoir. The device further comprises a control valve () which is controlled as a function of at least one control parameter representing a state of the circuit other than pressure in said main duct to which said replenishing valve () is connected, in order to connect the closing control chamber to the pressure-free reservoir or in order to isolate said chamber from said reservoir.
