Abstract
This invention relates to a system for regulating a liquid in a circuit, with the system comprising: a plug valve comprising at least one inlet and one outlet, the plug comprising an internal passage through which is intended to pass the liquid flowing from the inlet to the outlet of the valve when the valve is open at least partially, an expansion reservoir in communication with the liquid flowing in the circuit and intended to contain liquid and a compensating gas, characterized in that the plug comprises at least partially an expansion channel which has at least one lateral opening located on a lateral face of the plug and which is conformed to provide a permanent communication between said lateral opening and the expansion reservoir, the valve being conformed in such a way that: at least when the valve is closed: the lateral opening is in direct communication with the liquid coming from the inlet or from the outlet of the valve, when the valve is open at least partially, the lateral opening cooperates with an inner wall integral with a body of the valve in such a way as to form a conduit in communication on the one hand with the expansion reservoir and on the other hand with th…
