Abstract (en)
[origin: EP0195335A2] In the device, a compensation container is provided, in the interior of which there is a bladder (11). Excess water can be conducted out of the system into the bladder via pipes (15, 16). In the event of low pressure, water comes out of the compensation container via pipes (15, 17, 18) into the system. A spill valve (2) and a pump (4) are provided. In the event of excess pressure in the system, the spill valve (2) opens and lets water into the compensation container (14). If there is low pressure in the system, a manometric switch (3) switches the pump (4) on, which pumps water out of the compensation container into the system. At the same time, a time pulse is initiated in the electronic control device (5) and causes the pump (4) to be switched off depending upon time rather than on pressure. <IMAGE>
