1. An apparatus for filling containers with liquid product, said apparatus comprising a product vessel and a filling element arranged below said product vessel, wherein said filling element comprises a filling-element housing, a dispensing opening, an actuator, a liquid valve, a liquid duct, a valve plunger, a liquid valve body, a gas tube, a first gas-duct, a first gas-valve, a second gas-valve, a gas-valve body, a valve seat, a second gas-duct, a valve face, and a valve opening, wherein in operation, liquid product partially fills said product vessel, thus defining a liquid space occupied by said filling product and a first gas-space above said liquid space, wherein said filling-element housing comprises said liquid duct formed therein, said liquid duct connecting to said liquid space, wherein said dispensing opening is disposed on an underside of said filling-element housing, said underside facing away from said product vessel, wherein said liquid valve comprising said valve plunger and a liquid valve body, wherein said valve plunger is aligned coaxially with a filling-element axis, wherein said liquid-valve body is provided on said valve plunger, wherein said liquid-valve body is movable along said filling-element axis to open and close said liquid valve, wherein said gas tube is provided on said valve plunger, wherein said gas tube, in operation, extends into a head space of a container that is arranged to be filled at said filling element, wherein said valve plunger and said gas tube cooperate to define said first gas-duct, wherein said first gas-duct extends through said valve plunger and through said gas tube, wherein said first gas-duct has an upper end that extends into said first gas-space of said product vessel and a lower end that opens into an interior of said container, wherein said first gas-valve is disposed along said first gas-duct, wherein said first gas-valve comprises said gas-valve body, wherein said gas-valve body interacts with said valve seat, wherein said valve seat is configured in said first gas-duct, wherein said first gas-valve transitions between an open and closed state in response to said actuator, wherein said second gas-duct is formed through said gas-valve body, wherein said second gas-duct is configured to at least temporarily engage said first gas-duct in a fluid-tight manner, and wherein said gas-valve body comprises said valve face and said valve opening, wherein said valve face and said valve opening cooperate to form said second gas-valve, and wherein, when said second gas-valve opens, a flow of gas through said first and second gas-ducts enters said container.
