1. A method of filling bottles or similar containers with a liquid under counterpressure, using a filling machine which has, on a rotor, a plurality of filling elements, a bowl that is common to the filling elements, whereby the interior of the bowl forms a liquid space which is occupied by the liquid being bottled and a headspace above the liquid for an inert gas under a pressure or a filling pressure, and at least one return gas duct which is common to the filling elements or to each of a group of filling elements, whereby before the filling, the interior of the container is pressurized by means of a controlled gas path of each filling element with inert gas originating from the headspace of the bowl and at the filling pressure, and during the filling at least some of the inert gas is displaced from the containers by the incoming liquid into the at least one return gas duct, wherein the individual container is pressurized from at least one additional gas duct that functions as a gas sink and is common to the filling element or a group of filling elements, which additional gas duct is connected by means of at least one gas connection to the headspace of the bowl. 2. The method according to claim 1, wherein at least the pressurization of the containers and the filling of the containers are performed under counterpressure by controlling the gas paths of the filling elements such that, taking into consideration a gas exchange between the filling elements, the quantity of inert gas taken from the additional gas duct during the pressurization is greater than the quantity of gas displaced from the bottles into this additional gas duct during the filling under counterpressure. 3. The method according to claim 2, wherein inert gas is fed in a controlled manner to the headspace of the bowl to maintain the filling pressure. 4. The method according to claim 3, wherein the additional gas duct that functions as a gas sink has a volume which is significantly greater than the volume of the rotor-side gas connection that connects this gas duct with the headspace of the bowl. 5. The method according to claim 4, wherein the containers are pressurized exclusively from the additional gas duct that functions as a gas sink. 6. The method according to claim 5, wherein during the filling of the containers, some of the inert gas is also displaced by means of a controlled gas path of each filling element into the additional gas duct that functions as the gas sink. 7. The method according to claim 6, wherein the pressurization is preceded by a partial pressurization of the containers by mans of a controlled gas path of the individual filling element from the return gas duct. 8. The method according to claim 7, wherein before the pressurization or before the partial pressurization, there is at least one purging of the containers via controlled gas paths of the filling elements with inert gas. 9. The method according to claim 8, wherein the container is flushed with inert gas from the return gas duct. 10. The method according to claim 9, wherein before and/or after the purging via controlled gas paths of the filling elements, the container which is in sealed contact with the respective filling element is evacuated. 11. The method according to claim 10, wherein carbon dioxide gas is used as the inert gas, and under certain operating conditions, return gas can be conducted by means of a controlled gas path from the additional duct to the return gas duct or from the connecting line to the return gas duct. 12. The method according to claim 11, wherein there is at least a one-time evacuation or purging of the container prior to the filling of the container. 13. A rotary filling arrangement for the filling of bottles or similar containers with a liquid under counterpressure, with a bowl which is provided on a rotor that can be driven in rotation around a vertical machine axis, whereby the interior of the bowl forms a liquid space which is occupied by the liquid being bottled and a headspace above the surface of the liquid being bottled for an inert gas under a pressure or a filling pressure, with a plurality of filling elements located on the periphery of the rotor, each of which has a fluid duct which is in communication with the liquid space of the bowl and a discharge opening with a controlled liquid valve, with at least one common return gas duct on the rotor which is common to the filling elements or a group of filling elements, and with controlled gas paths realized in the filling elements, by which gas paths the individual container to be filled and located in sealed contact with a filling element can be pressurized with an inert gas at the filling pressure from the headspace of the bowl, and which makes possible a removal of the inert gas displaced from the containers during the filling at least partly to the return gas duct, wherein on the rotor for the filling elements or for each group of filling elements at least one common additional gas duct that functions as a gas sink is provided, which is in communication by at least one gas connection with the headspace of the bowl, and with which the filling elements are in communication with their controlled gas paths which effect the pressurization of the containers. 14. The rotary filling arrangement according to claim 13, wherein the additional gas duct that functions as a gas sink has a volume which is greater than the total volume of the rotor-side gas connection which connects this gas duct with the headspace of the bowl. 15. The rotary filling arrangement according to claim 14, wherein the at least one additional gas duct is in constant or substantially constant communication with the headspace of the bowl. 16. The rotary filling arrangement according to claim 15, wherein the filling machine comprises an arrangement for the controlled feeding of inert gas into the headspace of the bowl for the maintenance of the filling pressure. 17. The rotary filling arrangement according to claim 16, wherein on the rotor, at least one vacuum duct which is common to the filling elements or to a group of filling elements is provided, to which the filling elements are connected with at least one controlled gas path which is realized in the filling elements. 18. The rotary filling arrangement according to claim 17, wherein one gas duct is common to the gas paths realized in each filling element, which gas duct empties into the interior of the container that is located in sealed contact with the related filling element. 19. The rotary filling arrangement according to claim 18, wherein the discharge opening of each filling element is realized in the form of a ring or partial ring so that it encircles a container-side opening of the gas duct which is common to the gas paths. 20. The rotary filling arrangement according to claim 19, wherein the filling elements are filling elements without filler tubes, there is a controllable connecting line between the additional duct and the return gas duct and/or the connecting line and the return gas duct, and an arrangement is provided for the evacuation and/or purging of the container.
