Abstract (en)
[origin: EP0366997A1] Method for deaerating an installation for filling containers (2) with a metered amount of liquid not including any air by means of a metering pump (9), in which two control valves (11', 12') arranged at the inlet of a filling tube (4) are intermittently opened and closed, and the liquid (17) is conveyed via a buffer container (13). <??>In order to prevent the faulty filling of initial production material at the beginning of the filling operation, and in order to be able to specify as accurate a switched-on period as possible for the actual filling operation, it is provided according to the invention that, in order to deaerate the filling tube (4) and the metering pump (9) connected thereto, two control valves (11', 12'), connected in series, are controlled separately from each other in such a way that when the vacuum is generated in the buffer container (13), both control valves (11', 12') are opened; after the majority of the air has bubbled off upwards, firstly the upper control valve (12') and, after a period of time which can be set, the lower control valve (11') are closed; and then the upper control valve (12') is opened and, after a further time interval, is closed. <IMAGE>
