Abstract (en)
[origin: EP0945686A2] The pressurizer has an expansion tank (1) having a liquid-container chamber connected via a connecting pipe (3) to a heating or cooling circuit. An overflow valve (5) is positioned on an overflow pipe (4) leading to the chamber. The overflow pipe branches off from the connecting pipe or is connected to the heating or cooling circuit. A pump (6) pumps liquid from the chamber into the connecting pipe, and is situated inside the chamber which is formed by an extensible bubble (2) or is defined by a membrane in the expansion tank.
