This invention relates to a system for regulating a liquid in a circuit able to reverse the direction of the circulation, with the system comprising: a regulating valve comprising at least one inlet and one outlet and comprising a movable obturator the position of which makes it possible to adjust the flow rate of the liquid through the valve, an expansion reservoir in communication with the liquid flowing in the circuit and intended to contain liquid and a compensating gas, characterised in that: the expansion reservoir is connected to the circuit by the intermediary of the valve and in such a way that the expansion reservoir communicates with at least one from among the inlet and the outlet of the valve regardless of the position of the obturator, with the position of the obturator being independent of the pressure of the fluid in the expansion reservoir. The invention also relates to a circuit integrating this system as well as a use of this system. |
