Abstract (en)
[origin: EP0902239A2] A first valve (15) in the circuit also provides degassing. When pressure drops below a minimum operating pressure in the water circuit (21), a mechanical bypass valve (19) closes automatically. The pump (14) and the bypass valve are matched to one another so that, during a degassing procedure is a storage tank (22), a normal pressure is obtained when the first valve is open.
