1. A filling device for containers, particularly beverage bottles, comprising a filling unit by way of which different media, including a product to be bottled, can be one of supplied, discharged, or a combination thereof, and a return gas pipe which is contained in the filling unit and is displaceable in linear fashion relative to the filling valve by means of an electromagnetic positioning drive, the electromagnetic positioning drive (P) being a linear motor composed of a stationary stator housing including at least one linear motor winding and of a rotor coupled to the return gas pipe and arranged in the stator housing in a rotor bore, wherein the linear motor is a commercial linear motor formed with one of inner, outer, or combination inner and outer food-grade surface linings that are resistant to the media processed in the filling device, and wherein the linear motor with the stator housing and the rotor bore is constructionally integrated into the filling device with formation of a flow path for at least one medium. 2. The filling device according to claim 1, wherein the stator housing is lined with stainless steel. 3. The filling device according to claim 1, wherein the stator housing is mounted between a connection body and a valve housing having the return gas pipe (R) passing therethrough. 4. The filling device according to claim 1, wherein the rotor is arranged with a play in the rotor bore and is guided via guide elements which with an inner wall of the rotor bore define a medium passage extending between both ends of the stator housing. 5. The filling device according to claim 1, and wherein a control electronics of the linear motor is contained in the stator housing. 6. The filling device according to claim 1, wherein a coupling is provided between the return gas pipe and the rotor. 7. A filling device for containers, particularly beverage bottles, comprising a filling unit by way of which different media, including a product to be bottled, can be one of supplied, discharged, or a combination thereof, and a return gas pipe which is contained in the filling unit and is displaceable in linear fashion relative to the filling valve by means of an electromagnetic positioning drive, the electromagnetic positioning drive (P) being a linear motor composed of a stationary stator housing including at least one linear motor winding and of a rotor coupled to the return gas pipe and arranged in the stator housing in a rotor bore, wherein the coupling is provided between the return gas pipe and the rotor, and wherein said coupling has dimensions smaller than those of the rotor bore, and can be moved with at least a section of the return gas pipe into the rotor bore. 8. The filing device according to claim 1, and wherein the rotor stoke of the linear motor is up to about 100 mm. 9. A filling device for containers, particularly beverage bottles, comprising a filling unit by way of which different media, including a product to be bottled, can be one of supplied, discharged, or a combination thereof, and a return gas pipe which is contained in the filling unit and is displaceable in linear fashion relative to the filling valve by means of an electromagnetic positioning drive, the electromagnetic positioning drive (P) being a linear motor composed of a stationary stator housing including at least one linear motor winding and of a rotor coupled to the return gas pipe and arranged in the stator housing in a rotor bore, wherein in every filling cycle of the filling device the linear motor either one of programs the return gas pipe or drives it into different positions, the various positions being variable in response to time or, in the case of a rotating filling device, in response to the distance, expediently through a control electronics which may directly be assigned to the linear motor. 10. The filling device according to claim 3, wherein the rotor is lined with stainless steel. 11. The filling device according to claim 3, wherein the connection body is for one of vacuum application, pressure relief, or a combination thereof for the container. 12. The filling device according to claim 3, wherein the return gas pipe is for one of return-gas, product flow, pre-stressing-medium flow, correction-medium flow, or combinations thereof. 13. The filling device according to claim 4, wherein the rotor is guided at both ends. 14. The filling device according to claim 6, wherein the coupling is a releasable coupling. 15. The filling device according to claim 9, wherein one of the different positions is for lowering the return gas pipe down into a flushing position provided at a low level.
