A filling machine for filling liquid into containers (10) has a filling valve (25) for each container (10), which valve is actuated by a control device (19) by means of a trigger pulse (Z). In order to increase the precision of the liquid quantity (M (is)) filled into the containers (10) with regard to a desired fill quantity (M), it is proposed that the control device (19) adds up partial volumes (.DELTA.M), which are produced as a function of liquid pressures (P1) measured, the time intervals (.DELTA.t) between the individual pressure measurements, and a pressure/through flow characteristic curve of the filling valves (25). As soon as the sum of the partial volumes (.DELTA.M) has exceeded a limit fill quantity (M (max)), the control device (19) stops the trigger signal (Z).

[ What is claimed and desired to be secured by Letters Patent of the United States is:] [1.] A process for filling containers (10) with a liquid under pressure (P1) which comprises supplying a liquid contained within a pressurized reservoir (35) to a distributor (30) connected with said pressurized reservoir so as to completely fill the distributor with liquid, simultaneously supplying the liquid from said distributor to respective filling valves, measuring the pressure of the liquid contained within said distributor, transmitting the measured pressure (P1) to a control device (19) to which a signal representative of a desired fill quantity has been directed to produce a trigger output (Z) of said control device, directing the trigger output (Z) to each of said filling valves to simultaneously actuate each of said filling valves to fill said liquid in respective containers, continuously measuring the pressure (P1) at particular intervals (.DELTA.t) during the filling said containers, calculating actual filled fill quantities (M) from a sum of partial volumes (.DELTA.M), which sum is produced taking into account the respectively measured pressure (P1) of the liquid, the time intervals (.DELTA.t) between the individual pressure measurements, and a pressure flow characteristic curve (k) of the filling valves (25), and stopping the trigger signal from the control device (19) to the metering valves (25) when a fill limit quantity (M (max)) has been obtained.
