Patent ID: 8602070

Claim:
A device for filling containers, comprising: a filling material feeder; at least one dosing system connected to said feeder to receive filling material therefrom, said dosing system having a flow path with a dosing valve therein, said dosing valve being openable at least for a duration of a dosing process to deliver dosing amounts of filling material to containers via at least one filling line; a bypass diaphragm valve in said flow path downstream of said dosing valve for optionally producing a suction action on said flow path and through said filling line, said bypass diaphragm valve having a diaphragm forming a movable control element with opposite first and second control sides; a control activating said bypass diaphragm valve depending on dosing processes ended by closing of said dosing valve; and a choke site between said dosing valve and said filling line constricting said flow path during the dosing processes, said movable control element being in a region of said choke site and defining a width of said flow path depending on position settings, said movable control element being transferable by deflection thereof to an open position widening said flow path at said choke site by forming a bypass of the choke site to produce the suction action upon application of a negative pressure to said second control side of said moveable control element and being transferable to a closed position with said first control side delimiting the flow path through said choke site.
