An apparatus for filling containers with a product includes a filling element, a supply line that supplies the product, a switching valve, a control valve, a vessel that is disposed between the switching valve and the control valve, and a volumeter that is disposed between the switching valve and the control valve. The vessel supplies a pre-metered quantity of the product for discharge via the switching valve to the filling element, the quantity having been pre-metered by the volumeter. The supply line provides the product to the vessel at a first flow rate. Discharge of the product through the switching valve and into the filling element occurs at a second flow rate that exceeds the first flow rate, the first and second flow rates being volumetric flow rates.
An apparatus for filling containers with a product, said product being a liquid filling-product, said apparatus comprising a filling element, a supply line that supplies said product, a switching valve, a control valve, a vessel, and a volumeter, wherein said volumeter is disposed between said control valve and said vessel, wherein said vessel is disposed between said switching valve and said volumeter, wherein said vessel supplies a pre-metered quantity of said product for discharge via said switching valve to said filling element while said container is being prepared for filling by at least one of evacuation and pre-stressing of said container, said quantity having been pre-metered by said volumeter, wherein said supply line provides said product to said vessel at a first flow rate, and wherein discharge of said product through said switching valve and into said filling element occurs at a second flowrate that exceeds said first flow rate, said first and second flow rates being volumetric flow rates, wherein said apparatus further comprises a discharge line that leads to said filling element, wherein at least one of said discharge line has a cross-sectional area that is greater than that of said supply line and said apparatus further comprises means for imposing pressure on said product in said discharge line.
A method for filling containers with a product, said product being a liquid filling-product, said method comprising providing said product at a first flow rate, using a volumeter that is disposed between a switching valve and a control valve to pre-meter a quantity of said product for discharge via said switching valve into a filling element, storing said quantity in a vessel that is disposed between said switching valve and said volumeter, and discharging said quantity from said vessel into said filling element at a second flow rate that exceeds said first flow rate, said first and second flow rates being volumetric flow rates, wherein said volumeter is disposed between said control valve and said vessel, said method further comprising selecting a cross-sectional area of said supply line and selecting a cross-sectional area of a discharge line through which said product is discharged such that said cross-sectional area of said discharge line is greater than that of said supply line or imposing pressure on said filling product in said discharge line to cause said second flow rate to exceed said first flow rate, wherein using said volumeter to pre-meter said quantity of said product comprises using said volumeter to pre-meter while said container is being prepared for filling by at least one of evacuation and pre-stressing of said container.
