To enable filling a pressure tank with a fluid without having to interrupt the use of the pressure tank, a method is provided for filling a pressure tank with a fluid from a refill tank that is disposed higher, whereby the tanks are interconnected via a gas connecting line and a fluid feed line. The method includes the regulation of the pressure in the pressure tank via a proportional valve disposed in a gas inlet line of the pressure tank, while the connecting lines to the refill tank are closed, the adjustment of the pressure in the refill tank to the pressure in the pressure tank, and the opening of the connecting lines between the refill tank and the pressure tank. Furthermore, an apparatus for carrying out the above method is provided.

1. An apparatus for filling a pressure tank, which has an outlet line, said apparatus comprising: a refill tank that is disposed higher than said pressure tank and is connected with said pressure tank via a gas connecting line and a fluid feed line; a pressurized gas supply; a proportional valve, disposed in a gas inlet line that communicates with said gas connecting line, for introducing a pressurized gas from said pressurized gas supply into at least one of said pressure tank and/or into said refill tank; a first valve that is disposed between said proportional valve and said pressure tank but not in a connection between said proportional valve and said refill tank; a second valve that is disposed between said proportional valve and said refill tank but not in a connection between said proportional valve and said pressure tank; and a third valve, which is disposed in said fluid feed line. 2. An apparatus according to claim 1, wherein a first pressure sensor is disposed in said outlet line of said pressure tank, and wherein said first pressure sensor communicates with a control unit that determines a desired pressure value for said proportional valve with the aid of measurement results of said first pressure sensor. 3. An apparatus according to claim 2, wherein a second pressure sensor is disposed in said gas inlet line. 4. An apparatus according to claim 1, wherein a differential pressure sensor is disposed between said gas inlet line and said outlet line. 5. An apparatus according to claim 1, wherein said refill tank is connectable with said gas inlet line and said fluid feed line via coupling elements. 6. An apparatus according to claim 5, wherein said coupling elements are provided with sensors. 7. An apparatus according to claim 5, wherein said second and third valves are automatically closable by release of said coupling elements. 8. An apparatus according to claim 5, wherein said coupling elements are quick or snap-type couplings. 9. A method of filling a pressure tank, which is provided with an outlet line, with a fluid from a refill tank that is disposed higher than said pressure tank, wherein said pressure tank and said refill tank are interconnected via a gas connecting line and a fluid feed line, said method including the steps of: while said gas connecting line and said fluid feed line to said refill tank are closed, regulating said pressure in said pressure tank with a pressurized gas, from a pressurized gas supply, via a proportional valve disposed in a gas inlet line that communicates with said gas connecting line; closing said gas inlet line between said proportional valve and said pressure tank; regulating a pressure in said refill tank to said pressure in said pressure tank via said proportional valve; and opening said gas connecting line and said fluid feed line between said refill tank and said pressure tank. 10. A method according to claim 9, wherein said pressure in said pressure tank is regulated to a desired pressure value that is determined as a function of measurement results of a first pressure sensor that is disposed in said outlet line of said pressure tank. 11. A method according to claim 10, wherein said desired pressure value is not altered as long as said gas inlet line is closed between said proportional valve and said pressure tank. 12. A method according to claim 10, wherein as long as said connecting lines between said refill tank and said pressure tank are opened, said desired pressure value is determined as a function of said measurement results of a differential pressure sensor that is disposed between said gas inlet line and said outlet line of said pressure tank. 13. A method according to claim 9, which includes the step of measuring said pressure in said gas inlet line.
